As mentioned, I tried using the Epson 24 pin generic driver. I am not sure if this is a PPD or a foomatic filter or what. All I know is that it is listed as a printer type along with postscript, raw, and text. When I use this driver, the output of the printer is garbage - characters beyond normal ASCII printing(128+).

The parameters in /etc/printcap are used no longer.

This job does Foomatic from www.linuxprinting.org instead of Magigfilter 

or Apsfilter.  If you install Foomatic it produces PPD files for all 
printers and places them under /usr/share/cups/model
The PPD files contain information what to do with the Postscript file
send to CUPS. Then Foomatic calls Ghostscript with certain parameters.

Here you will find some Epson printers. Try e. g. LQ-2550 or 850.
