A printer test file is included on the BARR/3270 distribution disk(s). This file verifies that the printer is correctly connected to the PC and that the printer and PC are functioning together. Using the printer test file is helpful for diagnosing the following problems:
incorrectly set DIP switches or configuration data in the printer
incorrectly wired printer cable
inconsistent serial port baud rate mode
printer hardware error
The printout of the printer test will detail the individual printer test patterns.
To eliminate any question about BARR/3270’s operation, run the first test using DOS to print the file. Follow the directions below.
Insert BARR/3270 distribution disk in drive A.
Copy the file PRINTER.TST to LPT1.
Use the MODE command to set serial port COM1. Copy the file PRINTER.TST to COM1.
BARR/3270 supports XON/XOFF flow control. This prevents loss of characters that may occur during this test.
