The file operators in PostScript work only with file systems that
are directly available to the PostScript interpreter.  If your
printer had a hard disk attached to it, you could open arbitrary
files.  In your setup, there is no way for the PostScript
interpreter to "climb back up" the serial connection to access
the file system on your host computer (the PC).

In Display PostScript environments, the interpreter actually runs
on the host computer, and has access to the file system.

Unfortunately, you're out of luck in your situation.
