You referred to an "Epson 9900".

Epson Stylus Pro 9900 – Support

This seems to be a very old printer. The manual has chapters for "Printing With Mac OS X 10.4" and "Printing with Mac OS X 10.5." Those are operating systems that Apple released during the final days of PowerPC-based Macs, and the early days of Intel-based ones.

For a printer from that long ago, it would not be surprising if the manufacturer had simply stopped providing drivers that were compatible with new versions of the operating system. It is very common to have to "thank" the company who sold you your printer for failing to maintain drivers, and for basically, forcing you to buy a new printer.

In this particular case, it looks like Epson might still be providing drivers. Have you tried going to the Epson support site, selecting "macOS 15.x" for operating system, then downloading and installing the "Printer Driver v13.26" dated 11/11/24 that is on Epson's site?

If you have installed that driver, and it does not work, then all I can suggest is to contact Epson and urge them to fix their driver.

It is not sufficient to just install the driver and expect the device to work. You need to select the printer in the System Settings > Printers & Scanners panel, right-click on that printer name and choose either of Reset Printer… or Reset Printing System…, acknowledge on the subsequent challenge dialog that you want to remove the printer, and then click Add Printer, Scanner, or Fax… button.

On the Add Printer panel, select the printer and in the Use selector, choose your newly installed printer driver for the 9900, and then click the Add button. Now, the printer has access to the new driver and you should attempt to print something.

I’ve used three different Epson printers on Sequoia with no problems. I’ve never installed any Epson printing software as they are all AirPrint compatible. What model are you having a problem with?
