Ask Max: Printer driver won't install
I'm trying to connect to an Epson Stylus Photo RX620 all-in-one (not my favorite piece of hardware, but it's what I've got). I've downloaded software from Epson's site, which supposedly will install drivers for Intel-based Macs under OSX 4.xxx. The installer seems to run fine, but when I go to Systems Preferences > Print & Fax > Add Printer > Print Using, the only drivers that are listed under "Epson" are the Gimp-Print beta drivers.
A whole bunch of likely-looking stuff exists in Macintosh HD > Library > Printers > Epson, but I don't have any idea what to do with that information.
(By the way, I did run Epson's "Uninstall" program before installing their "Install." I did disconnect the USB cable before installing, and I did restart the iMac after installing. In fact, I've all this several times.)
Something for you to try is resetting your printing system. You do this by opening the Printer Setup Utility: it's in the Utilities folder in the Applications folder. Then under the Printer Setup Utility Menu, select "Reset Printing System." That will take your system back to square one, in terms of printers, but then all you'll need to do is add the printer again. You should not need to reinstall the Epson software. You may want to restart the computer in between resetting the printing system and adding your printer.
