Why do I keep getting error message “error while printing”?

Thank you for the information.

This printer model appears to be almost twenty years old, but some drivers are still available from the manufacturer.

Are you using the latest printer driver?

Please note that somewhat different drivers/software may be offered in different regions.

If necessary, try resetting the printing system.

Reset the printing system on your Mac to solve a problem – Apple Support (UK)

Add a printer to your printer list so you can use it on Mac – Apple Support (UK)

There is a Problem Solving section in the user's guide (p 97ff).

Is it possible to print a test page directly from the printer, without a connected computer?

See Running a Printer Check on page 100.

OK, we now know that the printer as such seems to be working as it should. The original driver CD contains too old printer drivers (if installed, remove them), so you would need to download the latest from one of the above Epson sites. After that, try a printing system reset, and then add the printer using the new driver.

Also, make sure that you have backup copies of all important files (documents, photos, et cetera) before testing anything.

Always download from an official web site of Epson. There are several third-party "support sites" on the Internet with similar names, so be careful.

Hi,

First of all, it is important to know the exact printer make and model.

Also, are you using the MacBook Air 13" and macOS 12.6 (Monterey) in your profile?

How is the printer connected?

Please post back with this information.
