Problem

Symptoms: @PJL Enter Language prints when the customer uses the HP LaserJet IIIP printer driver to print to an HP LaserJet IIIP printer. Solutions: The customer had a TSR called CONTEXT.SYS loaded in the CONFIG.SYS file. This program monitors the printer port and sends a @PJL Enter Language command to the printer. The customer remmed out the command line for the TSR to correct the problem. How/Why: First, verify that the customer is not using the HP LaserJet IIISi printer driver. Next, print to the screen by changing the printer port to CON (Shift-F7, S, 3, 2, 8). In this case, printing to the screen showed that WP was not sending this @PJL Enter Language command to the printer (when WP prints to the screen, you can see the codes that the printer driver normally sends to the printer). Printing from DOS also caused the same string to be sent to the printer. This proved that a TSR was sending this command. The customer's CONFIG.SYS showed that a program called Context, which is the HP TSR for the PostScript Plus cartridge was used. This program sends auto- switching codes to the printer.
