Hello Living Fossil,
Next, try the guidance from Solve printing problems on Mac - Apple Support which may be helpful. For instance, there may be a printer update from the manufacturer. The following section is from the article above.
"Make sure you have the latest software
Make sure you have the correct version of your printer’s software (also called its printer driver). If necessary, install the latest printing software that came with the printer or from the manufacturer’s website. If you’re using a printer that another user is sharing, make sure you’re both using the same version of the printer software.
- On your Mac, to find out which version of printer software you’re using, choose Apple menu > System Settings, then click Printers & Scanners
in the sidebar. - Click the printer in the Printers list on the right, then check the Driver version.
Contact with the printer manufacturer to see if you have the latest driver version.
If you’re using a network printer or a printer connected to your Mac, make sure you have the latest version of the software for the printer. If you still have problems, try a different version of printer software.
If you’re using an AirPrint-enabled printer, check with your printer’s manufacturer to see if any updates are available for your printer model."
After that, you might also try resetting the printing system if needed. Check out Reset the printing system on your Mac to solve a problem - Apple Support.
All the best.
