CHAPTER 6 TROUBLESHOOTING

Setting Up the Printer for DOS (For HL-730 series Only)

Question

I cannot print from my application software.

The printer prints, but it prints incorrect information. Sometimes it prints a couple of characters and then ejects the page, etc.

The printer does not print when I press the Print Screen Key.

(Data lamp On)

The printer prints the first part of my document but does not print the last page.

(Data lamp On)

How can I change the User settings or default settings of the printer?

Recommendation

∙Check if the DOS application software interface settings match that of your printer: for example, if you are using a parallel printer cable, you would most likely set your DOS software printer port to LPT1.

∙Check if the printer has any printer alarms active.

∙If the serial interface is used, make sure that the RS-232C serial interface is selected with the slide switch. Make sure that the interface settings are correctly set up with the proper DIP switches. Make sure the serial parameters of baud rates, parity and stop bits match between your application software and the printer.

This is an indication that your application printer emulation setting and the printer’s emulation do not match. Check in your application software which printer you have selected to make sure the printer is set up correctly. Remember this printer emulates three widely used printer selections: HP LaserJet IIP, Epson FX-850, and IBM Proprinter XL. Try setting the printer into HP emulation and then select the HP LaserJet IIP printer in your application software.

Press the panel switch. The data has been sent to the printer but the printer did not receive the Page Eject command: print screens do not send this command.

This was a common problem with database software and spreadsheet software when not correctly set up. The data has been sent to the printer but the printer did not receive the Page Eject command. Press the panel switch to eject the page. Then check with your software supplier on how to add a Page Eject (or Form Feed) command to the end of your print job.

Use the remote printer console (RPC) program.
