Operation Problems” on page 42. Connecting the Printer to Your System You can connect your printer to a PC, a local area network, an AS/400 (or other midrange computer), or a mainframe. This section tells you how to connect your printer to any of these systems.
Connecting Your Printer to a PC You can connect your printer to either a serial port or parallel port on your PC. You must provide the correct cables for connecting the printer. See the following sections for cable information. Contact your Intermec representative for ordering assistance if you do not have the appropriate cables.
For help on cabling and communications, see the manual that comes with the twinax adapter card. Note: If you are using a midrange computer other than the AS/400, refer to your system documentation for information on cabling and setting up communications. Helvetica CondensedHelvetica EasyCoder 3400e Bar Code Label Printer User’s Manual...
• Motor controllers • Switch gears If any of these items are near your printer, you may want to try the following suggestions to reduce the effects of electrical noise: • Always use shielded cable. Connect the cable and shield to the metal backshells on the cable connectors and fasten the connectors to the serial ports using screws.
For example, if you want to change the media type to thermal transfer, set DIP switch 8 on the bottom bank of switches to the on position. 3 Turn the printer power off and then on for the configuration changes to take effect.
After connecting the printer to your system, you need to test communications. The easiest way to test communications is to set the printer to Data Line Print mode, which is part of Test and Service mode, and send a character string down from your system.
Page 26
Note: An example of using DOS to verify printer communications follows this procedure. 6 To enter normal Print mode, turn the printer power off and then on again. If this procedure does not work, make sure that the DIP switches match the serial port configuration of the system and that you have the printer cable securely plugged into the correct port of your system.

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 create labels by downloading formats (designs) and data with IPL commands. You can use the printer to perform any function or activate any feature of the printer except for those features or functions that you set with the DIP switches. See the IPL Programming Reference Manual for more information.

There are limits to the number of formats, fonts, graphics, or pages that you can store in the printer. You can define up to 16 fonts, but there may not be enough room depending on the amount of memory being used for other purposes.
This rate in turn affects the throughput of the entire printing process. The printer begins imaging the label as soon as it receives the command to select a format. Since the printer starts imaging the label so early, the chance that the imaging process will be unable to keep up with the print speed decreases and throughput improves.
If the label prints, the image band setting is optimal. You do not need to perform any more adjustments. If the number of image bands is too low, the printer aborts the label before printing is completed and attempts to reprint the label at the slowest speed (2 ips) with the highest number of image bands (20).
Using Test and Service Mode This chapter explains the different procedures you can perform while the printer is in Test and Service mode. Use Test and Service mode on the printer to print test labels, perform special procedures, and change select configuration commands.
The function the printer is currently executing terminates, and the printer performs the new function. The printer remains in Test and Service mode until you turn the power off and reset the DIP switches. The printer executes all functions as soon as you select them.
