Hi @Foxhole72,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Reset the printer:

• Turn the printer off using the power switch, and then wait at least 30 seconds.
• Turn the printer on and wait for it to initialize.
• If you are using a surge protector:
• Turn the printer off.
• Remove the surge protector.
• Plug the printer directly into the wall socket, and then turn the printer on.
• If the error persists, turn the printer off and disconnect any network or USB cables.
• Reconnect the cables and turn the printer on.
• If the printer returns to Ready, check the firmware version. Update the firmware if a newer version is available.
• For more information, go to HP LaserJet Pro - Update the printer firmware.
• If the error is intermittent, attempt to isolate the issue to something specific in the environment, such as a specific file or connection type. For example, the error message appears when printing a PDF file or webpage.
• If printing a webpage, try a different browser.
• If printing a PDF file, try one of the following:
• Use the PCL 6 driver and set Print Data Optimization to Optimize for Raster.
• NOTE:
• Use the model-specific (not UPD) PCL 6 driver.
• Open Devices and Printers, right-click the printer, and select Printing Preferences.
• Click the Advanced tab, and from the Print Data Optimization drop-down, select Optimize for Raster.
• Click Apply, and then click OK.
• Use the PCL 6 Driver and enable the Send TrueType as Bitmap option.
• NOTE:
• Use the model-specific (not UPD) PCL 6 driver.
• Open Devices and Printers, right-click the printer, and select Printing Preferences.
• Click the Advanced tab, and under Printer Features, enable the Send TrueType as Bitmap option.
• Click Apply, and then click OK.
• Use the PCL 5 driver to print.
• If the error persists, contact your HP-authorized service or support provider, or contact customer support at www.hp.com/go/contactHP.

Hope this helps! Keep me posted for further assistance.
