I think a search for the latest driver from the epson website might help.
A few printer models back when my photo 700 didn't like a new environment I spent a fortune on the Epson help line. The relevant point seemed to be that Epson "then" were unenthuisiastic about their own Status Montior software and told me to use just the updated driver!
It didn't solve my problem but a new driver might solve yours.
Afterthoughts...... I assume it is USB.. or is it parallel, in which case is the LPT1 port set to ECP in the BIOS?
