  • Now you need to filter the files, showing only files with the width .gpd. To do this, click on the arrow next to "Type."
  • Select the GPD file.
  • Modify the file names to suit your needs. However, before renaming these files, we suggest that you create backup copies first.

  • After starting your system, try to print a document again. Check if the PCL XL error has disappeared.

Enable the "Send true type as bitmap" option.

  • To change the printer settings, go to Control Panel> Hardware and Sound.
  • Open Devices and Printers.
  • Right-click the icon for your printer and select Print Settings.
  • Open the Advanced tab.
  • In the Printer Features section, you must enable the "Send true type as bitmap" option.
  • Confirm by clicking OK and try printing again.

Adjust printer settings

Once the Printing Preferences window is open, click the Advanced tab at the top of the window. From there, select the "Make the most of text and vector" option in the "Print Optimization" menu. This tells your printer that it can accept and print different media content at the same time from the standard text data. Once you have confirmed these settings, your printer should be able to print the desired documents without displaying a PCL XL error.

Try a test print of the last document where the error occurred. If you keep getting the same message, try restarting the printer to make sure the changes have been implemented correctly. At this point, you should be able to successfully complete the printing of your document. Regardless, if you continue to experience problems, you may be able to get additional help by contacting Hewlett Packard's online support teams.

Note that this problem is almost always caused by printer setup alternatives, not the printer hardware itself. With this in mind, you can probably fix this problem without replacing your printer.
