4044-XXX Parallel Port Service Check 1. Perform a print test to make sure the printer prints correctly. 2. Be sure the printer cable is designed for bidirectional printing. 3. Be sure the user application is set up correctly. Improper set up can prevent establishing a communication link with the printer. 4. Try enabling the parallel port pull-up resistors. Go to "Parallel Mode 1" on page 3-8. Try printing a test page after enabling resistors. If the printer still does not print, disable the resistors. 5. If the internal print test page prints correctly, the user application/printer driver is set up correctly and the correct bidirectional parallel cable is installed, yet the printer still fails to print on command from the host, replace the controller board.
