NOTE:

If your network is managed by a network administrator or an information technology (IT) department, it would be considered a complex network. You should have the responsible person perform any network-related administrative tasks.

Tips provide additional insights about a topic or procedure (such as, why you may want to do something or a faster way to perform an operation). For example:

TIP: Specifying print settings in a multi-user environment

If the Horizon imager is accessed by multiple users, it is typically better for individual users to enter print values through the DICOM application interface rather than change the default settings through the control panel.

Cautions and Warnings

Cautions alert you to actions or situations that could cause harm to equipment or data. For example:

CAUTION

made by other users. Use caution when changing default settings.

Any changes you make to the imager default settings will also affect prints

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying this imager.

NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. REMOVAL OF LABELS, COVERS, OR ENCASEMENT FASTENERS VOIDS THE WARRANTY.

THIS APPARATUS MUST BE ELECTRICALLY GROUNDED.

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS IMAGER TO RAIN OR MOISTURE.

xxii Preface

EQUIPMENT IS NOT TO BE USED AS A COMPONENT OF A LIFE SUPPORT SYSTEM. Life support devices or systems are devices or systems that support or sustain life, and whose failure to perform can be reasonably expected to result in a significant injury or death to a person. A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

Laser Warning

The Horizon imager uses a laser to read barcode information on the media cassettes. The laser module is a 670-nm, 1.26-mW device. As such it has been found to comply with the 21 CFR 1040.10 and

1040.11 and IEC 60825 laser standards as a low power Class 1 device.

For safety reasons, the laser is turned on only for a short time when a cassette is inserted. Still, one should use caution and never stare at the laser beam, should avoid exposure to the laser, and should never override any of the interlocks and safety mechanisms. These measures are taken for your protection.

WARNING Use of controls or adjustments to the performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

The laser apertures are marked with a single label, shown below. There are three apertures that correspond to the three cassette locations, one for each, on the same side of the Horizon imager as this label.

AVOID EXPOSURE

LASER RADIATION IS EMITTED

FROM THIS APERTURE

Safety interlocks are marked by the following label. They are located on the same side of the Horizon imager as this label.

Potential for Radio Frequency Interference on Imager Operation

Both portable and mobile RF communications equipment can affect medical electrical equipment, including the Horizon imager. Keep such RF communications equipment out of the immediate area.

Potential for Radio and Television Interference

The Horizon imager generates and uses radio frequency energy, and if not installed and used properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception. It has been type tested and found to comply with Class B emission limits for a computing device in accordance with the specifications in Subpart J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operating in a commercial environment. Operation of the equipment in a residential area is likely to cause interference, in which case the user, at his own expense, will be required to take whatever measures may be appropriate to correct the interference. If your imager does cause interference to radio or television reception, you are encouraged to try to correct the interference by one or more of the following measures:

•

Reorient the receiving antenna

•

Relocate the imager with respect to the receiver

Location Precautions

•

The imager’s operating ambient temperature range is 15–30ºC (59–86ºF), with a relative humidity of 10%–80%.

•

If the imager is moved quickly from an extremely cold place to a warmer one, condensation is likely to form. Do not use the imager if condensation has formed. Wait until the condensation has evaporated. You can speed up the evaporation time by moving the imager to a dryer location.

•

Ventilation slots and holes are provided on the sides and rear of the imager. Place the imager on a hard level surface and locate it at least 10 cm (4 in.) from walls to ensure proper ventilation.

CAUTION

•

Do not place imager in a high humidity or high dust area.

Adequate ventilation is required for proper operation of the imager.

Airborne dirt particles can cause image quality problems. Avoid placing the imager in areas where ventilation ducts, open doors, or frequent passers-by might expose the imager and media to high levels of debris.

•

Do not locate the imager in hot-springs areas where hydrogen sulfide and acidic ions are likely to be generated.

•

Do not locate the imager where there are oily fumes and vapors.

•

Do not locate the imager in direct sunlight.

•

Do not locate imager near sources of high RF energy.

•

Do not locate the imager where it might be subject to jarring or vibrations, such as a table or desk in a high-traffic area. Jarring and vibrations can affect the print quality of images.

xxx Preface

Cleaning Precautions

•

Many plastic components are used in the imager’s construction. Coat flecking and deformation is likely to occur if the imager is wiped with chemical dusters, benzene, thinners, insecticides, or other solvents. Rubber and PVC materials left in contact with the imager for extended times will cause damage. Never use petroleum-based solutions or abrasive cleaners.

•

To clean the imager cover, first power off the imager using the

(power) key at the control panel, then turn the rocker switch in the back to the 0 (off) position, then unplug the imager. Clean the cover with a soft cloth slightly moistened with a mild soap and water solution. Allow the cover to completely dry before operating the imager again.

•

Printed images that are subject to prolonged exposure to sunlight, ultraviolet light, or extreme heat may degrade in image quality. (For example, printed sheets should not be stored in an automobile on a sunny day.) Precautions should be used to avoid prolonged direct exposure.

File Transfer via FTP and LPR

•

Different users who share a user name when transferring files to the imager may cause unpredictable and erroneous printed output. The imager associates information with the user name. Each user should have a unique user name when connecting to the imager via FTP and LPR.

Color Management

•

Image settings—including gamma, contrast, Dmax, saturation, and MCM™ (Medical Color Matching™)—are intended to compensate for differences that may occur between image acquisition and image printing. These filters allow you to accurately render the final printed image. You should use care when applying these filters to avoid over compensation.

•

The Default User Settings set at the control panel will potentially affect prints made by all users. Use caution when changing the default settings.

Preface

Image Scaling

•

Scaling an image will filter the original image data and add or remove information, which may affect the accuracy of the final printed image. The amount of information added or removed will also var y with the magnitude of the scale factor applied. This can also affect the accuracy of the final printed image. You should be aware of the properties and limitations of each scaling algorithm and select the appropriate algorithm for the task.

Horizon Imager Technical Manual xxxiii

Hardware Variations

•

Components used in the imager may vary, causing differences in image quality. The thermal process of producing a print utilizes many components that are calibrated to provide consistency between imagers. There are subtle differences between imagers that can cause print variations. These differences usually apply to thermal print head calibration. Other factors such as age, usage, heat, mechanical wear, and shipping can affect image color and quality.

Indications for Use

The Codonics, Inc., family of Horizon imagers produces radiological quality, hardcopy output. They can produce color prints on dye-diffusion film and paper, and grayscale prints on direct thermal film and paper. They are designed to convert digital image data from a host computer into hardcopy prints.

xxxiv Preface

Film prints are suitable for diagnostic use when viewed on a light box designed for such purposes. Color film prints, and color and grayscale paper prints, have the quality, texture, and feel of standard photographic materials. All Horizon imagers create prints electronically, without optics, wet chemicals, or a separate fusing process.

The exact media types and sizes supported will vary, depending on the specific model purchased.

IP Addressing Basics

IP Addresses

IP addresses are used to uniquely identify hosts on a TCP/IP network.

IP addresses are 32-bit binary numbers, consisting of four octets. For example:

10000000 00001010 00000010 00011110

To make these addresses readable for us, they are typically expressed in decimal notation of the binary address shown above is:

128.10.2.30

The values in each of the four sections of the dotted decimal address can range from 0 to 255, because that is the range of an 8-bit binary number.

Your network is connected to the Internet.

In this case, your IP addresses must be unique within the entire Internet. These numbers are assigned to companies and Internet service providers (ISPs). If your network is handled by a network administrator at your organization, you should see the network administrator for the IP address to use for the Horizon imager. If you are handling the network and connecting to the Internet through an ISP, the ISP will provide you with a block of IP addresses to use for the devices on your network.

•

Your network is part of a WAN (that is, there are multiple LANs or subnets).

In this case, unless your network is behind a firewall, your IP addresses must be unique within the entire WAN. If your network is behind a firewall, the IP addresses must still be unique for all devices in the network behind the firewall. These IP addresses are typically assigned by a network administrator at your organization. You should see the network administrator for the IP address to use for the Horizon imager.

Subnetworks and Subnet Masks

Many organizations with multiple LANs assign IP addresses according to those physical networks. In such a configuration:

•

A portion of the IP address represents the Internet part (for example, the first two dotted decimal numbers) and the physical network part (for example, the third dotted decimal number). This is referred to as the

subnetwork

portion of the

address.

•

A portion represents the host (for example, the fourth dotted decimal number).

Horizon Imager Technical Manual 2-5

Network Settings

For example, say an organization has been assigned the IP network address 95.200.0.0. This is the address that hosts on the Internet at large would use. Internally, the organization assigns addresses based on the physical network to which a host is connected. For example, all hosts on one physical network would be assigned addresses in the form 95.200.1.

defined. In the subnet mask, the bits that uniquely identify the subnet are set to 1; the bits that correspond to the unique host ID portion are set to 0. Referring to our previous example, the organization’s subnet mask would be 255.255.255.0 (11111111.11111111.11111111.00000000 in octet format).

To determine what subnet mask to use for the Horizon imager:

•

If your network is maintained by a network administrator,

see

the administrator for the subnet mask used at your site.

•

If you are managing a network that is connected to the Internet through an ISP,

your ISP will provide you with the

subnet mask to use.

•

If you are managing an isolated network not connected to any others,

use the Horizon default subnet mask

255.255.255.0

For information about how to define the subnet mask for the Horizon imager, refer to “Specifying the Imager’s IP Addresses” on page 2-10.

Horizon Imager Technical Manual 2-7

Network Settings

The Horizon Imager and DHCP

Dynamic Host Configuration Protocol (DHCP) is an Internet protocol that allows the dynamic assignment of IP addresses from a DHCP server. DHCP saves a network administrator from having to manually configure an IP address to each host on a network. When a host connects to the network, the DHCP server automatically assigns it an IP address. When the host disconnects from the network (for example, shuts down), the address is returned to the pool of available addresses to be assigned to other hosts. With DHCP, a host will typically get a different IP address each time it connects to the network.

Since it is a printing device, the Horizon imager needs a static, explicit address. This allows remote hosts to know exactly what address to use to send print jobs. For this reason, the Horizon imager does not support the DHCP protocol; its IP address must be manually defined.

2-8 Network Settings

Assigning Multiple IP Addresses with IP Aliasing

One effective way to use the Horizon imager’s ability to print on multiple media types and sizes is to configure the sending workstation with several “virtual” printers with the Horizon imager’s IP address. Each of these virtual printers can then be assigned to use a different Horizon media type and size. Chapter 4 provides detailed explanations of how to do this for DICOM.

Unfortunately, some systems do not allow multiple printers to be defined with the same IP address. To address this limitation, the Horizon imager includes a feature called imager to have up to five IP addresses assigned to it. This is done by defining a base IP address and then the number of IP addresses you want to assign. The imager will then be assigned a block of IP addresses by incrementing the last octet of the base IP address by one.

For example, if you define a base address of 192.168.1.1 and the total number of IP addresses at 3, then the imager will assign itself the IP addresses 192.168.1.1, 192.168.1.2, and 192.168.1.3.

Define that device’s IP address, gateway IP address, subnet mask, and so on

•

Add the Horizon imager’s IP address to the list of IP hosts with which the device will communicate

Just how you do this varies, depending on the device and its operating system. For this reason, you will have to refer to the documentation that comes with the device for specific instructions.

Configuring DICOM Printing

To support sending print jobs from DICOM applications, you must:

•

Configure the Horizon imager’s DICOM information in the DICOM user application. The Horizon imager configuration information is provided in the next topic.

•

Determine the method for allowing users to select the features supported by the Horizon imager. For more information, refer to “Methods for Selecting Media” on page 4-3.

NOTE: If you are running DICOM Lite on the imager and see connection errors at the

console or workstation from which you are sending print jobs, you may require more connections than DICOM Lite provides. Contact Codonics technical support (for contact information, refer to page xx in the Preface) for assistance.

Configuring DICOM Printing

To properly configure a DICOM application to support printing to the Horizon imager, you need its TCP port number and the Called AE Titles that can be used to identify the imager:

Methods for Selecting Media

The Horizon imager supports features and settings that may not be implemented in existing DICOM user applications. An example of this is the wide variety of media type and size combinations supported by the Horizon imager. In this topic, we examine some of the possible implementations for selecting media type and size, and present solutions for working within potential DICOM application limitations.

For more information about the Horizon print parameters and how they map to DICOM attributes, refer to “Horizon–DICOM Print Information” on page 4-7.

The Horizon imager can receive print parameter values from a variety of sources, including the DICOM attributes sent with the print job, Horizon Job Settings files, and the Default Media and Default User Settings menus at the control panel. To fully understand how to implement Horizon printing solutions, you need to understand how the imager determines which parameters to use if they are coming from multiple sources. For more information about this topic, refer to “Parameter Selection Process” on page 6-28.

Configuring DICOM Printing

Application Allows Media Selection of Supported Horizon Types and Sizes

If the DICOM application already supports selecting media types and sizes (say, from drop-down lists), and they include the types and sizes supported by the Horizon imager, no alternate implementations are needed. Users would simply select the desired Horizon media type and size from within the application.

Horizon Imager Technical Manual 4-3

If the DICOM application allows you to define multiple printers, all pointing to the Horizon imager, you could also:

•

Create a printer for each combination of media type/size supported by your Horizon imager, and set the defaults for each printer accordingly.

For example, let’s say your imager supports 14 x 17-in. blue film and 8 x 10-in. clear film. You could create two printers, name them “Horizon Blue Film 14x17” and Horizon Clear Film 8x10,” and set their media type and size accordingly. Users would then know which printer to use for both available media.

•

Create a printer for each media type, but let users select the size.

For example, let’s say your imager supports all sizes of blue and clear film. You could create two printers, name them “Horizon Blue” and “Horizon Clear,” and set their default media types accordingly. Users would then know which printer to use for a given media type, but select the appropriate size themselves.

If you are defining multiple printers that point to the Horizon imager, you would have to configure the following parameters for each printer:

•

The Horizon imager’s IP address

•

The Horizon imager’s TCP port number—

•

The Called AE Title (for the Horizon imager, the default Called AE Title is

Print_SCP

If the application or operating system does not allow you to define multiple printers with the same IP address, you could use the Horizon imager’s IP Aliasing feature. This feature allows you to assign multiple IP addresses for the same imager. For more information, refer to “Assigning Multiple IP Addresses with IP Aliasing” on page 2-9.

Media Selection Supported, but Not Horizon Types or Sizes

It is possible that the DICOM application allows users to choose a media type and size, but one or more types or sizes supported by the Horizon imager are not in the list of choices. The solution you use to overcome this limitation depends on the type of user you are:

•

If you are a developer [

(VAR) or system integrator], you may be able to modify the application’s properties or configuration file to add the Horizon types and sizes to the list of choices. If this is not possible, you would have to use one of the solutions suggested in the following alternate solutions topics.

•

If you are a site administrator or other type of power user

who is responsible for supporting use of the imager, you would have to use one of the solutions suggested in the following alternate solutions topics.

Brief Overview of Job Settings Files

Job Settings files are sets of job, sheet, and image parameters— including the media type and size—that are stored in the imager and can be applied to a print job. With DICOM, a Job Settings file can be specified using the name of the Job Settings file as the Called AE Title. For a complete explanation of Job Settings files, refer to Chapter 8.

for example, for a value-added reseller

Configuring DICOM Printing

Each imager is preloaded with system Job Settings files that define each of the available Horizon media type/size combinations (but no other job, sheet, or image parameters). A list of these system Job Settings files is included in Appendix B. Note that the media-specific type/size combinations supported by an imager depend on the media options purchased for that imager.

Horizon Imager Technical Manual 4-5

Using Job Settings Files to Specify Media Type and Size

Following are some alternative solutions for using Job Settings files to set the media type and size

if the DICOM application allows you to define multiple printers pointing to the same Horizon imager

•

You could create a printer for each of the media type/size combinations supported by your Horizon imager, and use the corresponding system Job Settings file name as the Called AE Title. When the imager receives a DICOM print job, it will use the media type and size specified in the Job Settings file whose name matches the Called AE Title. For example, if you wanted to support printing to 14 x 17-in. create a printer that used the Job Settings file name

DirectVista

paper, you would

14x17-dvp

as its Called AE Title.

•

There are two special system Job Settings files called

defaultgrayscale

and

defaultcolor

. These Job Settings files cause the imager to use the media type and size defined for grayscale and color in the Default Media menu at the control panel. So, for grayscale images, you could create a printer in the DICOM application with the Called AE Title

defaultgrayscale

, then set the media type and size you want to use for grayscale images in the Default Media menu. When the imager receives a DICOM print job with the Called AE Title

defaultgrayscale

, it will use the media type and size specified for grayscale in the Default Media menu.

If the DICOM application allows you to define only one printer that points to the Horizon imager,

solutions include the following:

You could create a custom Job Settings file at the control panel called

•

You could keep changing the printer’s Called AE Title to match the Job Settings file that defines the media type and size you want to use for each print job.

Using the Default Media Menu to Specify Media Type and Size

As an alternative to using Job Settings files, you could use the Default Media menu at the control panel to select the media type and size. The Default Media menu allows you to specify the default media type and size to use for grayscale images, and the default to use for color images.

The limitation to this approach is that all grayscale images will be printed on the same media type and size, and all color images on the same type and size, unless and until they are manually changed using the Default Media menu at the control panel.

The Horizon imager supports PostScript print jobs from any Windows workstation running Windows 98, Me, NT 4.0, 2000, or XP. The tasks required to support PostScript printing to the imager are:

•

Installing the Horizon imager PostScript driver and PPD file onto the workstation.

•

Adding the Horizon imager as a Windows desktop printer.

This is done using the standard Windows “Add a Printer” wizard, or by a “Point and Print” connection as a network printer. When adding the imager as a desktop printer, you will need to select the Horizon imager’s PostScript driver and PPD file. For information about adding the Horizon imager as a desktop printer, refer to the appropriate Horizon PostScript Technical Brief.

Horizon Imager Technical Manual 5-1

Once the imager has been added as a desktop printer, users can print to it from any application using the standard Windows Print function. For more information about sending PostScript print jobs and setting Horizon PostScript parameters (such as media type and size), refer to the

Horizon Imager User’s Manual

Applications That Generate Non-Standard PostScript

The Horizon imager uses Microsoft Windows print drivers that generate PostScript commands to transfer page layout information to the imager. These print drivers are primarily intended for use with application programs that utilize standard Graphics Device Interface (GDI) print driver interface calls to construct pages of graphics and text for output to the imager.

When used with applications that conform to the standard GDI methods of constructing a page, the advanced configuration settings of the Horizon print drivers will control the media selection and image processing capabilities of the imager. The advanced configuration settings are communicated to the imager as DSC (Document Structuring Conventions) comments embedded in the PostScript job stream. These comments are unique to Horizon and will not work on other imagers. The DSC comments are recognized by the PostScript-compatible interpreter in the Horizon imager and set the appropriate media and image processing settings to use for that print job.

5-2 Configuring PostScript Printing

Some applications bypass the traditional GDI methods of constructing pages. Although rare, these applications generate their own PostScript commands, ignoring the usual print driver mechanisms. The custom PostScript job stream is sent directly to the imager using a special GDI print driver call. Applications using this technique usually create print jobs that omit the PostScript DSC comments used by Horizon to control media selection and image processing. When a Horizon imager receives such a job, the imager will not know which media to use or how to render the image on that media. The most common problem when DSC comments are missing from the PostScript job stream is printing on the wrong media or rendering the image at the wrong size for the media.

The best way to determine if the DSC comments are missing is to print to a file from the application in question using the Horizon print driver. After the file is saved, open it with a text editor and look for a DSC comment in the first 500 lines of the file. Sample DSC comments are shown in the following example:

featurebegin{ %%BeginFeature: *CXMediaType CVPaper %CDXFeature: *CXMediaType CVPaper %%EndFeature }featurecleanup

Configuring PostScript

featurebegin{ %%BeginFeature: *CXMediaSize A %CDXFeature: *CXMediaSize A %%EndFeature }featurecleanup

All DSC comments describing Horizon advanced configuration features begin with the letters “CX.” As shown in the previous example, the entries CXMediaType and CXMediaSize would be present if the application program used the Horizon print driver in the usual manner. If these entries are not in the file, then the application is probably using the print driver in a non-standard way. It is important to make sure that non-standard applications are generating proper PostScript output. It is outside of the scope of this document to describe the PostScript language; however most PostScript files are human-readable and have the string “%!PS” at the beginning of one of the first lines of the file.

Horizon Imager Technical Manual 5-3

Printing

Solution for Processing Non-Standard PostScript File

The workaround for this problem is to add Horizon Job Setting file information to the LPR port on any Windows system that sends print jobs to Horizon. The LPR port transfers PostScript print jobs from the Windows operating system to Horizon logical device 7 on the Horizon imager. (For more information on logical devices, refer to “Horizon Logical Devices That Support PostScript Jobs” on page 5-12.) Appending a Job Settings file name to logical device 7 will force the imager to use the print parameters set in the Job Settings file. The parameters set in a Job Settings file provide the same functionality as the missing DSC comments in the PostScript print job. Parameters set in a Job Settings file take precedence over parameters set in PostScript DSC comments.

The easiest way to select a specific media type or size is to use one of the system Job Settings files that come preloaded with the Horizon imager. These files define all of the media type/size combinations supported by the Horizon imager (and only those parameters). Alternately, you can create custom Job Settings files that include other print parameters. For more information about Job Settings files, refer to Chapter 8. A complete list of the system Job Settings files is provided in Appendix B.

Once you have chosen a suitable Job Settings file, you need to run the Windows Add a Printer wizard to create a new desktop printer that points to the Horizon imager. When the wizard displays the Port Settings, enter the number 7 (specifying Horizon logical device

7), followed by a period and the name of the Job Settings file in the

LPR Queue

field. For example, entering queue name will force a PostScript job sent to this desktop printer (that is, the Horizon imager) to print on 8 x 10 film. The sample screen that follows shows the Port Settings tab in the Add a Printer wizard for Windows 2000.

If more than one media type/size combination is required, then you will have to create a separate desktop printer that points to the Horizon imager for each combination, defining the Job Settings file to use in the LPR Queue field as described in the previous paragraph.

Horizon Imager Technical Manual 5-5

Configuring PostScript

Printing

A final step is to make sure the Advanced Configuration Settings of the print driver are assigned to match the parameters set in the Job Settings file you are specifying. This will ensure that application programs that properly use the print drivers will work the same as non-standard applications that rely on the Job Settings file. As stated previously, parameters set in a Job Settings file take precedence over parameters set in PostScript DSC comments. Since most applications are well-behaved and will generate the appropriate DSC comments, it is important to have the media type and size consistently set for all applications. Refer to the Technical Brief for the Horizon Windows PostScript driver that you are using for information on how to set the default properties of the print driver.

It is also recommended that the Windows desktop printers be given names that indicate what they will do. For example, the printer that will always print on 8 x 10

DirectVista

blue film would have a name such as “8x10 Grayscale Blue Film.” For users, this will simplify selecting the correct desktop printer to print to the desired Horizon media.

pick the Horizon LPR printer that matches the set of Horizon parameters to use for the print job. This method requires that you create LPR printers that specify one of three Horizon logical devices that support PostScript files in the LPR printer definition.

Both of these methods require that you perform setup tasks so that users can access Horizon imager parameters that are not included in the generic set of PostScript parameters, including Horizon media types and sizes. The available methods are discussed in “Methods for Selecting Horizon Media Type and Size” on page 5-9. Additional topics related to implementing PostScript printing are included in other chapters in this manual:

Because Horizon parameters can be set in a variety of places (Job Settings files, the PostScript file, at the control panel, and so on), there is a hierarchy that the imager uses to determine which source takes precedence over the others.

Methods for Selecting Horizon Media Type and Size

The Horizon imager supports print parameters that are not included in typical PostScript parameter sets. An example of this is the wide variety of media type and size combinations supported by the Horizon imager.

When setting up the imager to support UNIX users, you will need to determine how you want to allow those users to select Horizon-specific print parameters such as media type and size, which in turn determines how to implement the support for these parameters.

Table 5-1 on page 5-10 describes the approaches you can take to select the various Horizon media types and sizes. Selecting other Horizon print parameters can be done using similar approaches.

Adding Horizon DSC Comments to the PostScript File

(developer only)

Horizon system Job Settings files allow you to specify each combination of Horizon media type and size. The appropriate system Job Settings file can then be specified during an FTP session or in the definition of an LPR printer to select the desired media.

For more information about Job Settings files, refer to Chapter 8. A complete list of the system Job Settings files is provided in Appendix B.

This is the Codonics-recommended solution, unless you can implement the Horizon DSC comments solution discussed in the last row of this table.

If a system Job Settings file is not specified, the Horizon imager assumes that the PostScript file is a grayscale image. The imager then uses the media type and size defined for Grayscale in the Default Media menu at the imager control panel. Instructions for using the Default Media menu is provided in the Horizon Imager User’s Manual.

You can specify Horizon media types and sizes, which are not covered by standard PostScript, by having your application set the parameters in DSC comments included in the PostScript file. The imager will then interpret the Horizon DSC comments to determine the media to use.

Pros: Provides most control and flexibility in selecting Horizon media.

Cons: Have to specify Job Settings file for each combination of Horizon media type/size to be used.

Pros: Parameters can be easily set at the control panel.

Cons: Have to manually change the media type and size for Grayscale in the Default Media menu if they do not match the media required for the print job about to be sent. Other users could get unexpected results for their print jobs.

Pros: Ability to set Horizon parameters within the PostScript file, instead of defining Job Settings files or changing the Grayscale settings in the Default Media menu for each print job.

(In addition to media type and size, there are other Horizon print parameters that are not supported in standard PostScript but which can be added by using Horizon DSC comments. Refer to Table 5-6 on page 5-21 for a complete listing of the special Horizon parameter DSC comments.)

PostScript files that contain Horizon DSC comments must be sent to Horizon logical device 7. For more information about the Horizon logical devices that can process PostScript files, refer to “Horizon Logical Devices That Support PostScript Jobs” on page 5-12.

5-10 Configuring PostScript Printing

Cons: Source application that generates the PostScript file must be modified to include the Horizon DSC comments, or comments must be added manually.

Sample Implementation

• For LPR printing, specify each system Job Settings file in three different LPR printer definitions. Explain to users which LPR printer to use for each of the three media type/size combinations.

Prior to each print job, users will have to use the Default Media menu at the imager control panel to change the Grayscale media to the desired media type/size.

If users are using a custom application to generate the PostScript file, you will have to modify the application to allow users to select between the three media type/size combinations, then include the corresponding Horizon DSC comments in the output PostScript file.

Another option is to manually edit each PostScript file to include DSC comments for the desired media type and size.

General PostScript Information

Horizon Logical Devices That Support PostScript Jobs

Generally, the Horizon imager i s comp atib l e with a n y PostScr ipt f ile that conforms to PostScript level 1, 2, or 3, and is tolerant enough to process many jobs that do not completely conform.

When sending images to the Horizon imager using FTP or LPR, the imager uses numbers—referred to as how to process the print job (for more information about Horizon logical devices, refer to Chapter 9).

There are three Horizon logical devices that support PostScript jobs sent using FTP or LPR printing, as explained in the following two topics.

Logical Devices 1 and 2

The imager will process a PostScript file submitted to logical device 1 or 2 as a PostScript job as long as there is a line that begins with the percent (%) character within the first 512 bytes of the file.

•

PostScript files submitted to logical device 2

NOTE: Logical devices 1 and 2 do not support processing PostScript files that include

are rendered as

Logical Device 7

Logical device 7 is reserved for processing PostScript files only. Because it processes all submitted jobs as PostScript, it is the most tolerant of the three logical devices in terms of conformance to PostScript specifications. Marginally compliant or noncompliant jobs that fail using logical devices 1 and 2 might print successfully using logical device 7. Logical device 7 is also the only logical device that can process PostScript files that include Horizon DSC comments.

PostScript files submitted to logical device 7 are rendered as defined in the PostScript file with no additional scaling.

Unlike logical devices 1 and 2, logical device 7 will print only the marked area of the image. That is, any area outside the image is cropped and will be printed using the specified background color. For more information about this topic, refer to “Image Cropping with PostScript Jobs” on page 5-14.

Printing

Image Cropping with PostScript Jobs

PostScript jobs generally define a white page that is the size of the printable area of the media, then place text, graphics, or bit-mapped images in the printable area.

When processing a PostScript file sent to Horizon logical device 1 or 2, the Horizon imager will crop the image data to the smallest rectangle that still includes all marked pixels in the image (marked pixels include white pixels, which will appear as no pixels). Unless a background color has been specified, the margin between the image area and the boundary of the printable area will print white.This can be a problem if the image should be printed on a black background, which is typically the case with film. The white margin will print between the image and the black background, as shown in Figure 5-1.

et edg

To eliminate the white margins, use logical device 7. Unlike logical devices 1 and 2, which will print the white margins, logical device 7 uses an automatic margin cropping feature that removes any white margins outside the region of marked pixels.

In addition to using logical device 7, developers could use the Horizon DSC comment

False

NOTE: Horizon DSC comments in a PostScript file take precedence over corresponding

print parameters defined in any other possible source except for Job Settings files. So, while printing to logical device 7 implies that the Crop Margin parameter is set to True, a CXCropMargin DSC entry in the PostScript file will take precedence.

Correct PostScript Page Size and Maximum Printable Areas for Horizon Media

To properly use the entire printable area on Horizon media, the PostScript file should use the correct Horizon page size and maximum printable area size measurements.

The correct page sizes are listed in Table 5-3. The largest printable areas are specified in Table 5-4 on page 5-17. The printable area offsets are illustrated in Figure 5-2 on page 5-18.

For an example of how to specify a Horizon media page size in a PostScript file, refer to the first few lines of code in the “Sample Horizon DSC Comments in a PostScript File” on page 5-24.

Horizon Print Parameters in DSC Comments

The information in this topic is provided if you want to implement support for Horizon print job parameters that are not standard PostScript and need to be implemented as DSC (Document Structuring Conventions) comments.

NOTE: PostScript files that contain Horizon DSC comments must be sent to Horizon logical

device 7.

NOTE: Horizon DSC comments in a PostScript file take precedence over corresponding

print parameters set in any other possible source except for Job Settings files.

Table 5-5 on page 5-20 lists the Horizon print parameters that can be set only in DSC comments in a PostScript file.

Table 5-6 on page 5-21 lists the Horizon print parameters that can be set in DSC comments, but can also be set by other means (for example, Job Settings files).

For a complete description of the Horizon parameters, refer to Chapter 6. To see a sample use of the Horizon DSC comments in an actual PostScript file, refer to “Sample Horizon DSC Comments in a PostScript File” on page 5-24.

Configuring PostScript

Note that the sheet orientation, the number of copies to print, and the layout of images on the sheet are handled using standard PostScript commands (not DSC comments).

Receive Tray

The Receive Tray parameter—1, 2, or 3—determines to which receive tray to output sheets for the job. The default is to use the receive tray that corresponds to the supply slot from which the sheets are pulled.

NOTE: This parameter is not settable at the control panel.

Priority

The Priority parameter determines the priority of the print job. Higher priority jobs are printed first.

Possible values are:

•

•

MEDIUM

•

HIGH

NOTE: This parameter is not settable at the control panel.

How the Imager Determines the Supply Slot

To determine from which supply slot to pull sheets, the imager looks in sequence from slots 1 to 3 for the media type/size specified in the print job. Once it finds a cassette with the proper media type/size, the imager pulls sheets from that cassette. The imager will continue pulling from that cassette for that media type/size until the cassette is empty, even if a similar cassette is subsequently loaded in a slot above that one.
