Sudden problem with Printing

4-2020

01:40 PM

I am using several HP LaserJet 2300 printers none of which were working since yesterday on Mac running Mac OS Mojave and Catalina.  These printers WILL run using Mac OS High Sierra. The workaround that allows my printers to work with Mojave and Catalina is to reinstall the printers using the "Generic PCL Printer option and Default printer list.

Do not feel alone here, there is currently a HP issue…And we are flooded with similar complaints
