Hi @Wellington44,

Thanks for engaging in HP support Forums! This is a wonderful location to converse with the community, get assistance and find tips!  I understand you are having issues with the HP OfficeJet printer printing strange characters. Don't worry as I have a few suggestions which should help you resolve this issue.

To provide you with an accurate solution, I'll need a few more details:

Have you tried to clean the cartridge contacts as well as the rollers

Have you tried to perform reset printing system on Mac?

In the meantime, let's try these steps here: 

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove USB cable, if present.

Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till warm-up period finishes and the printer is idle.

If you are using MAC OS, then try the steps here:

• Click the Apple menu icon, and then click “System Preferences”.
• Click “Printers and Scanner” / “Print and Scan” or “Print and Fax”.
• Right-click the blank space in the Printers list, and then click “Reset printing system”.
• Click “Reset” in the confirmation window.
• Enter an administrator username and password, and then click “OK”.
• Wait until the printing system is reset and no devices show in the Printers list.
• Restart your computer and then go back to System preferences – Printers and scanners.
• Click the “Add button” (+).
• Find, and then select the name of your printer from the printer list, and then click “Add” to add your printer.
• Click “Print Using...” or “Use”, and then select Secure AirPrint or AirPrint. Alternatively, you may select the name of your printer if available in that list.

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!

I hope you have a good day ahead,

And Feel free to ask your queries as this forum has some of the best people in the world available and ready to help.

Hi Jeet_Singh
