Post Script Printing

I can't not print any adobe files.  I'm on a MacOSX 10.2.6 box printing to a 
linux CUPS server. I saved several adobe files directly as a postscript files 
and tried to print it, but I can't even do that directly from the print server 
Linux Box (that's taking the OSX out of the equation).

I have an Epson Stylus Photo 2200 connected via usb that can print anything but 
adobe files. I also have a tektronix phaser 8200 connected via usb as well.  
it's a post script printer.  when i send it a command like 'lp -d Phaser 
Example.ps' it just spit out garbage (that's the linux or osx box too).

I'm not sure what is going on. If it was ghostscript, then the tektronix phaser 
would be able to print the postscript file correctly since it was a postscript 
printer(right?) and not the epson. but neither can print PS or interept data 
sent to it from a remost host sending it Adobefiles to be wrapped in PS. When 
this happens, the MacOS X box reports that 
"client-document-format-not-supported."

Is it cups?  Any ideas, at all? :/

The setup is A Gentoo Linux Box with ESP Ghostscript 7.05.6, CUPS 1.1.19, 
Gimp-print 4.3.20 (for the epson) and tk8200dp.ppd for the phaser8200.  I have 
checked the ppd on the http://www.cups.org/testppd.php webpage and it says 
PASS, but it just won't print.  I'm at a loss.  help, please.
