Troubleshooting PS Errors

The following situations are PS language specific and may occur when several printer languages are being used.

OTE

To receive a printed or screen displayed message when PS errors occur, open the Print Options window and click the desired selection next to the PostScript errors section.

Problem Possible Cause Solution

PostScript file can not be printed.

“This job contains binary data...” message appears.

A PS error page prints.

The optional Tray2 is not selected in the driver.

The PostScript option may not be installed.

The pure binary data option is not supported by the PostScript driver.

Print job may not be PS.

The printer driver has not been configured to recognise the optional Tray2.

• Print a configuration page and verify that the PS version is available for printing.

• If PostScript is not available, install the PostScript option. See “Installing Memory and PostScript DIMMs” on page F.3.

Open the Properties of the PostScript driver, click on

Advanced

option is not supported. Choose another.

Make sure that the print job is a PS job. Check to see whether the software application expected a setup or PS header file to be sent to the printer.

Common Linux Problems

Problem Possible Cause and Solution

I can’t change settings in the configuration tool.

I am using the KDE desktop but the configuration tool and LLPR won’t start.

I just installed this package but can’t find entries in the KDE/Gnome menus.

I get a “Some options are not selected” error message while editing the printer settings.

I can’t make a printer the system default.

You need to have administrator privileges to be able to affect global settings.

Maybe you do not have the GTK libraries installed. These usually come with most Linux distributions, but you may have to install them manually. Refer to your distribution’s installation manual for more details about installing additional packages.

Some versions of the KDE or GNOME desktop environments may require that you restart your session for the changes to take effect.

Some printers have conflicting settings, meaning that some settings for two options can’t be selected at the same time. When you change a setting and the Printer Package detects such a conflict, the conflicting option is changed to a “No Choice” value, and you have to choose an option that does not conflict before being able to submit the changes.

In some conditions, it may not be possible to change the default queue. This happens with some variants of LPRng, especially on recent RedHat systems that use the “printconf” database of queues.

When using printconf, the /etc/printcap file is automatically refreshed from the database of printers managed by the system (usually through the “printtool” command), and the queues in /etc/printcap.local are appended to the resulting file. Since the default queue in LPRng is defined as the first queue in /etc/printcap, therefore it is not possible for the Linux Printer Package to change the default when some queues have otherwise been defined using printtool.

The N-up setting does not work correctly for some of my documents.

LPD systems identify the default queue as the one named “lp”. Thus, if there is already a queue by this name, and if it doesn’t have any alias, then you won’t be able to change the default. To work around this, you can either delete the queue or rename it by manually editing the /etc/printcap file.

The N-up feature is achieved through post-processing of the PostScript data that is being sent to the printing system. However, such post-processing can only be adequately achieved if the PostScript data conforms to the Adobe Document Structing Conventions. Problems may arise when using N-up and other features relying on post-processing if the document being printed isn’t compliant.

Problem Possible Cause and Solution

I am using BSD lpr (Slackware, Debian, older distributions) and some options chosen in LLPR don’t seem to take effect.

I am trying to print a document in Landscape mode, but it prints rotated and cropped.

Some pages come out all white (nothing is printed), and I am using CUPS.

I can’t print to a SMB (Windows) printer.

Legacy BSD lpr systems have a hard limitation on the length of the option string that can be passed to the printing system. As such, if you selected a number of different options, the length of the options may be exceeded and some of your choices won’t be passed to the programmes responsible for implementing them. Try to select less options that deviate from the defaults, to save on memory usage.

Most Unix applications that offer a Landscape orientation option in their printing options will generate correct PostScript code that should be printed as is. In that case, you need to make sure that you leave the LLPR option to its default Portrait setting, to avoid unwanted rotations of the page that would result in a cropped output.

If the data being sent is in Encapsulated PostScript (EPS) format, some earlier versions of CUPS (1.1.10 and before) have a bug preventing them from being processed correctly. When going through LLPR to print, the Printer Package will work around this issue by converting the data to regular PostScript. However, if your application bypasses LLPR and feeds EPS data to CUPS, the document may not print correctly.

To be able to configure and use SMB-shared printers (such as printers shared on a Windows machine), you need to have a correct installation of the SAMBA package that enables that feature. The “smbclient” command should be available and usable on your system.

My application seems to be frozen while LLPR is running.

How do I specify the IP address of my SMB server?

Some documents come out as white pages when printing.

Most Unix applications will expect a command like the regular “lpr” command to be non-interactive and thus return immediately. Since LLPR is waiting for user input before passing the job on to the print spooler, very often the application will wait for the process to return, and thus will appear to be frozen (its windows won’t refresh). This is normal and the application should resume functioning correctly after the user exits LLPR.

It can be specified in the “Add Printer” dialogue of the configuration tool, if you don’t use the CUPS printing system. Unfortunately, CUPS currently doesn’t allow to specify the IP address of SMB printers, so you will have to be able to browse the resource with Samba in order to be able to print.

Some versions of CUPS, especially those shipped with Mandrake Linux before the 8.1 release, have some known bugs when processing the PostScript output from some applications. Try upgrading to the latest version of CUPS (at least 1.1.14). Some RPM packages for most popular distributions are provided as a convenience with this Linux Printing Package.

7.26

OLVING PROBLEMS

Problem Possible Cause and Solution

I have CUPS and some options (such as N-up) seem to be always enabled even though I don’t pick them in LLPR.

I configured a printer to print to a file, but I get “Permission denied” errors.

On my PCL (or SPL) printer, I sometimes get error messages printing instead of my document.

There may be some local options defined in your ~/.lpoptions file, which is manipulated by the lpoptions command. These options will always be used if not overridden by LLPR settings. To get rid of all options for a printer, run the following command, replacing “printer” with the name of the queue: lpoptions -x printer

Most printing systems will not run as the super-user but as a special user (usually “lp”). Therefore, make sure that the file you have chosen to print to is accessible to the user owning the spooler daemon.

Unfortunately, some Unix applications may generate noncompliant PostScript output that may not be supported by Ghostscript, or even the printer itself in PostScript mode. You can try to capture the output to a file and view the results with Ghostscript (gv or ghostview will allow you to do so interactively) and see if you get error messages. However, since the application is at probably fault, contact your software vendor to inform them of the issue.

Common DOS Problem

Problem Possible Cause and Solution

When using the printer in EPSON Dot Printer Environment, sometimes I can not get the output I want.

Change the emulation to EPSON in the Remote Control Panel. For detailed information about selecting printer settings in the Remote Control Panel, see page D.4.
