Hi Gwalagwala,
Welcome to the HP Forums, I hope you enjoy your experience!
I understand you are getting a PCL XL Error printing on the page.
I will be happy to help you.
To resolve this issue we will need to update the firmware on the printer.
I have included the URL to download, save and run the firmware update.

I believe that this will provide a resolution to your issue. Thank you.
