Very Computer

Hi,
 I have major problems with my printer setup. I have a Epson 640 and the
thing use to work good, but the options were limited. I thought I'd
install the 5.10 version of ghostscript and see if any new things showed
up for this printer. After I installed however when it comes time to
select a filter I only have 2 options shown, plain text and postscript
(in printtool). Before I did the new install, It
showed the Epson as a choice along with many others, now there are none
except the 2 mentioned. Any ideas? Thanks for any input. Doug
