Use this chapter to learn how to configure your 7421 printer, communicate with a PC, and print a test label with PrintSet.

Configuring the Printer

You are now ready to configure the printer by downloading data from the host to the printer. For your printer to operate most effectively, you need to configure:

• the media sensitivity number

• the print darkness

• the label gap sensors

Setting the Media Sensitivity Number

Media sensitivity is important because you use it to optimize print quality. The three digit media sensitivity number (MSN) specifies the amount of heat required by the printhead to image a label. The amount of heat that each roll of media or ribbon requires is unique due to different chemistries and manufacturing processes.

Intermec has developed heating schedules (the amount of heat required to image a label) to produce the highest possible print quality for Intermec media and ribbon combinations on Intermec printers. Look for the three digit media sensitivity number on:

• the side of the media roll. Use the last three digits (140 in the

example) of the 15 digit number stamped on the roll for the media sensitivity number.

• a small label attached to the roll of media.

• a small label attached to the plastic bag of your ribbon roll.

Your label may be different from this example, but it will contain the media sensitivity number.

Note: Some ribbon rolls have the media sensitivity number printed on the inside core.

Use this three-digit number to optimize print quality and print speed on your printer. You can achieve the best print quality on the printer by using only Intermec ribbon and media products. The default sensitivity setting for thermal transfer media is 567. For direct thermal media, the default sensitivity setting is 180.

To change the media sensitivity number with PrintSet

1. Start the PrintSet application software.

2. Click the Paper type button.

3. In the Print Quality Setup dialog box, enter your three-digit number in the Media Sensitivity Number field.

4. Click OK.

Setting the MSN for Intermec Media and Ribbon

For direct thermal media, use the three-digit media sensitivity number located on the roll of media to set the media sensitivity number. You can also use the values from the tables in the next section.

For thermal transfer media, you need to look in two places to determine the sensitivity number. The media sensitivity number on each roll of thermal transfer media or ribbon has an asterisk (*) in place of one of the digits. On thermal transfer media, the number contains the first and second digits, with an asterisk in place of the third digit. One the thermal transfer ribbon, the number contains the first and third digits, with an asterisk in place of the second digit.

To optimize the sensitivity number for thermal transfer media, you combine the digits like this:

Media or Ribbon Sensitivity Number Description

Thermal transfer media

Thermal transfer ribbon

56* The asterisk reserves the

third digit to identify the ribbon’s sensitivity number.

5*7 The asterisk reserves the

second digit to identify the media’s sensitivity number.

Setting the MSN for Other Media and Ribbon

If you are not using Intermec media and ribbon, or if you misplaced your packaging with the three digit-sensitivity number label on it, you can set an approximate sensitivity number. The first column of the Direct Thermal and Thermal Transfer Media Sensitivity Settings tables list the approximate sensitivity settings. To achieve acceptable print quality, enter the three-digit media sensitivity number (for example, 600).

If you are unsure of how to set the media sensitivity number, start with the highest setting, which provides the lowest energy (600 for thermal transfer and 400 for direct thermal), and work your way down until you achieve the best print quality.

Adjusting the Print Darkness

Use the print darkness adjust to fine-tune the darkness of print on your labels. The fine adjustments compensate for variations in the media (“lot to lot”), the printhead, or the printer. The darkness adjustment is similar to the dark adjust available on a copier. An increase in print darkness increases the energy to the printhead and results in darker print. A decrease in print darkness decreases the energy to the printhead and results in lighter print.

Set the darkness after you enter the media sensitivity number. You can adjust the print darkness from + 10 to -10.

To adjust the print darkness with PrintSet

1. Start the PrintSet application software.

2. Click the Paper type button.

3. In the Print Quality Setup dialog box, adjust the Print Darkness slider bar until the setting that you want appears underneath it.

Adjusting the Label Gap Sensor

The label gap sensor detects the gap between labels while they are being printed. The gap sensor automatically calibrates itself when you first turn on power to the printer. This adjustment compensates for manufacturing differences in label stock that may make it difficult for the gap sensor to detect the gap between labels.

To adjust the label gap sensor

1. Turn the printer power off.

2. Turn the printer power on.

The printer Power light flashes yellow and the printer advances to the next label. When the label gap sensor adjustment is complete, the Power light stops flashing and turns green.

Communicating With the Printer

Downloading is the universal term used to describe the transfer of information from the host to any connected peripheral device, such as your printer. When you transfer data from your printer to the PC or host, you are performing a process called uploading.

You can use several methods to download information to your printer. Use these products to communicate with your printer:

PrintSet Application Software Use the PrintSet application software to easily configure your printer from your PC. You can upload the current configuration settings, modify them, and then download them to your printer. PrintSet also lets you:

• download graphics and fonts.

• print test labels using resident fonts, user-defined bitmap

graphics, or resident bar code symbologies.

• allocate printer memory.

• download configuration files to multiple printers.

For help using PrintSet, refer to the online help portion of the application software.

Intermec Printer Language (IPL) Commands You can create labels by downloading formats (designs) and data with IPL commands. You can use the printer IPL commands to perform functions and activate features of the printer. See the IPL Programming Reference Manual for more information.

Third-Party Software You can use third-party software to set many of the printer parameters. You can use PrintSet or the IPL command set to configure the parameters that your software does not set.

Use your third-party software to create label formats and convert graphics into a user-defined character (UDC) format that the printer can interpret.

Printing a Test Label

If you would like to test your communications by downloading a label, follow the example below. Use the PrintSet application software to send a test label to the printer.

Communication Problems

If your printer is not receiving downloaded data, try the solutions in this table.

Symptom Possible Causes Solution

Printer does not communicate with the host.

Using Data Line Print Mode

Use Data Line Print mode to troubleshoot communications between the printer and the host, and to test the operation of the printer. When the printer is in Data Line Print mode, it prints out all downloaded data with the hexadecimal equivalent directly underneath it.

Incorrect communications parameters.

Damaged or incorrect I/O cable.

Use PrintSet to make sure that you have the correct communications parameters set (such as baud rate).

Check the connections at both ends or replace the cable. See Appendix B for cable information.

To enter Data Line Print mode

1. Turn the On/Off switch to the off position.

2. Press down and hold the Feed/Pause button while turning on the printer.

The hardware configuration test label prints out and the firmware program and version number are sent to the host. You are now in Data Line Print mode.

3. Send a few characters down from the host. The printer prints out your data with the hexadecimal equivalent directly underneath it.

4-6

Page 63

4. Hold the Feed/Pause button down to momentarily suspend the test. The printer prints a software configuration test label.

5. If you press the Feed/Pause button again, the pitch label prints.

To exit Data Line Print mode

1. Turn the printer power off.

2. Turn the printer power back on.

Preventing Data Loss

Several problems can cause data loss or communications problems on the printer. Data loss can result in printing errors or missing field data.

Hardware handshaking involves the use of a hardware wire. Software handshaking involves a two-way datalink between the devices. The two devices communicate with each other without losing data through the use of handshaking. The printer sends both forms of handshaking simultaneously when the printer’s input buffer is full. Any loss of data can cause printing errors or missing data.

Hardware handshaking uses pin 6 or pin 9 of the RS-232 interface to control data flow. When the printer is using Intermec Standard protocol, it holds pins 6 and 9 high when the printer is ready to receive data. For help on understanding printer protocol, see Appendix B, “Communications Reference.”

The printer holds pins 6 and 9 low when the printer is in one of these conditions:

• Buffer full

• Ribbon fault

• No label stock

• Label at peel-off bar

4-7

Page 64

Your printer uses XON/XOFF protocol for software handshaking. When the input buffer is full, the printer transmits an XOFF character. This action alerts the host to the fact that the printer buffer is full and cannot receive any more data. When the printer is ready to receive more data, it sends the XON character.

To check for communications problems

1. Check the cabling from the printer to the host system.

2. Check the interfacing of the devices that are communicating with the printer.

3. Check the printer for proper electrical operation of the I/O port.

4. Test to see that the host system is not overrunning the printer’s input buffer.

5. Check to see that the data string being sent to the printer contains the correct information.

Resetting the Printer to Factory Defaults

Use memory reset if you want to return the printer to its default configuration.

To reset the printer to factory defaults

1. Turn off the printer.

2. Lift the printhead and remove all label stock from the paper path.

3. Turn the printer on while holding down the Feed/Pause button.

4. When the print mechanism starts to move, release the Feed/Pause button and press it again. The Power light should now be flashing red.

5. Press and hold the Feed/Pause button down for 8 seconds or until the Power light stops flashing. The printer resets all parameters to their factory default settings.

About Communications

The 7421 printer supports both serial and parallel communications. Using the parallel interface with an IEEE 1284 parallel interface cable (Part No. 590124) provides the best performance.

Your printer has the following hardware and software requirements:

• The host computer must use the American Standard Code for

Information Exchange (ASCII) for data communications.

• A serial port or a parallel port must be available on the host if

you are connecting directly to the printer.

• The host must support the RS-232 or data communications

interface.

For information on configuring the host computer, port concentrator, or network controller, see the reference manual for the controlling device.

Serial Communication Protocols

Communication protocols are important because they determine the transmission standards for communications between the printer and the host. The printer and the host must use the same protocol and parameters to communicate properly. The printer supports the flow control and block transfer protocols described in the next sections. All of these protocols are point-to-point. Application programs and/or ROM BIOS determine which protocols your computer can support. For more detailed information, refer to the Intermec Data Communications Reference Manual (Part No. 044737).

Intermec Printer Standard Protocol

Intermec Printer Standard Protocol is a half-duplex protocol. All data transmission to the printer consists of status enquiry (ENQ), status dump (VT), or message blocks. Each message block starts with the Start of Text (STX) characters and ends with the End of Text (ETX) characters. Each message block must be 255 characters or less, including the STX and ETX characters.

B-3

Page 74

The printer returns its highest priority status when it receives a valid block (<STX> data <ETX>) or when it receives the status request command <ENQ>. When the printer receives the status dump command (<VT>), the printer returns all active status. The printer status response time ranges from 30 ms to 100 ms depending on the complexity of the received message block. In the case of a transmission error, the printer responds with a <NAK> and discards the entire message block.

The table below shows printer status conditions in descending order of priority:

Printer Status Character

Buffer already full GS Ribbon fault US No label stock EM Buffer now full DC3 Printhead hot SI Label at strip pin FS Skipping DC1 Printing DC1 Ready/Online DC1

Note: Do not confuse the Buffer now full <DC3> status with the XON/XOFF characters <DC1> and <DC3>.

When the printer returns Buffer Now Full (<DC3>) status, it accepts the currently received message block. At this time, the printer can accept short messages to allow parsing of immediate commands such as Reset (<DLE>) or Cancel Batch Printing (<EM>). However, if the printer responds with a <GS> to any message block, the buffer is already full and the printer discards the entire message block. In case of a transmission error, the printer discards the whole message block and responds with a Negative Acknowledgment (NAK). You should retransmit the message block from the host.

B-4

Page 75

XON/XOFF Protocol

XON/XOFF protocol uses the ASCII characters <DC1> (XON) and <DC3> (XOFF) to start and stop the flow of data from the host to the printer. The printer does not restrict the message length for XON/XOFF protocol. That is, the printer processes information as it is being downloaded and stops when there is no more information.

<STX> and <ETX> are optional characters. However, if you send an STX, the printer ignores all other characters until you send an ETX.

Intermec provides two versions of the XON/XOFF protocol. The Intermec version of XON/XOFF has the printer respond to each message with its current status. The other version conforms to generally accepted industry standards that include no end-ofmessage response being sent to the host other than XOFF. In addition, a DC3 is sent to the host if the printer is offline or if media fault occurs. An XON is sent on power up.

Since the printer uses DC1 and DC3 for data flow control, the printer status characters are different from those of the Standard Protocol.

Printer Status Character

Buffer already full GS Ribbon fault US No label stock EM Printhead hot SI Buffer now full DC4 Label at strip pin FS Label skipping DC2 Printing DC2 Ready DC2

If the host ignores the printer sending an XOFF, the printer resends an XOFF after receiving every 15 characters from the host. In the case of transmission error, the printer discards the characters with the error and keeps the rest of the message block.

B-5

Page 76

Hardware Protocol

The printer uses Ready/Busy and DTR (data terminal ready) of the RS-232C interface to indicate the printer’s status. You can configure Ready/Busy and DTR independent of each other and independent of the software protocol you select for the serial port. You can set each pin to one of these four settings: default, high, flow control, and Ready/Busy.

When you set the pin to high, it stays high as long as the printer is powered up.

When you set the pin to flow control, the pin is high when the printer status is ready. The pin is held low when the printer is offline or if the buffer is full.

When you set the pin to Ready/Busy, the pin is high when the printer status is ready. The pin is held low when the printer is in one of these conditions:

• Offline

• Buffer full

• No label stock

• Ribbon fault

• Label at strip pin

When you set the pin to default, it uses flow control if the serial port is set for XON/XOFF protocol. If you are using Intermec Standard protocol, the printer uses Ready/Busy.

User-Defined Protocol

The printer provides the capability to change protocol characters. However, users may not define their own protocol. You can substitute characters you want to use as protocol characters, but the rules for the chosen protocol do not change. The printer does not use any protocol characters that you replace with the NUL character. One table of protocol characters exists. You may redefine these characters to create a table that all of the protocols can use. One possibility for the user to redefine protocol characters might be the replacement of control characters with printable characters.

B-6

Page 77

Note: Please use caution when replacing control characters with printable characters. You cannot replace one control character with more than one printable character.

The following table lists the protocol characters that you can redefine and the protocols they affect:

Character Protocol Affected

SOM IN STD, XON/XOFF EOM IN STD, XON/XOFF DLE IN STD, XON/XOFF XON IN XON/XOFF XOFF IN XON/XOFF NEG OUT STD DLE OUT STD XON OUT XON/XOFF XOFF OUT XON/XOFF PROTO-CMD 1 STD, XON/XOFF PROTO-CMD 2 STD, XON/XOFF
