How do I get Epson WF 2650 to work on Imac with 10.15.7 version

Hi, DeafLinux.

Welcome to the Apple Support Communities. We’re glad you decided to reach out about updating the printer drivers on your Mac. If we understand correctly, you’re attempting to update the drivers for your Epson WF-2650 Series. According to Printer and scanner drivers for Mac, you should be on version 9.80. You can check the version by opening System Preferences > Printers & Scanners > [your printer] > Options & Supplies to see your current version. You may not need to update the driver.

If you confirm that you do need an update, are you following the guidance outlined here to update?

Hi,

In the macOS 10.15.x Downloads section at https://epson.com/Support/Printers/All-In-Ones/WorkForce-Series/Epson-WorkForce-WF-2650/s/SPT_C11CD77201, you will find an Epson Software Updater v2.6.0, a Printer Driver v10.33, etc. Could anything here be of interest?

It is also worth noting that the WF-2650 supports the driverless AirPrint technology.

Software from the printer manufacturer may add functionality.

You don't say what "problem" you are having trying to install your printer's driver, is it's hard to respond. Installing a printer driver is normally just a simple matter of downloading the file and then installing it. If a compatible driver is not available, then that is a different problem. You might visit the site below where many drivers are available for older printers.
