^^^^^^^^^^^^^^^
Your printer is probably fine. You aren't sending it postscript encoded
files, that's all. You have to convert text files to postscript.
Sun has a package called transcript which provides postscript support for
troff and text files. One of the programs is enscript, which converts a
text file into postscript. These are all available to the normal user.
There is also a printer filter that the System Administrator can install
that looks at the first line of the file to see if it is a postscript file.
(All postscript files begins with %!PS-Adobe-, or at least %!) If the file
is postscript, it sends it to the printer unchanged. If not, then it runs
it through enscript.
If you don't need troff support, there are a number of PD text to
postscript filters floating around. Use one to format text and/or install
it as a printer filter.

The Postscript "bibles" are three books from Addison-Wesley and written by
Adobe Systems. They are:
Postscript Language Reference Manual (the red book)
Postscript Language Program Design (the green book)
Postscript Language Tutorial and Cookbook (the blue book)
