Thanks for the help (again).

I have made my printcap look like the one you posted Frederick.

Should I now be able to lpr files to my printer?  I can't. I still get 
"unknown printer", both with lpr and lp....

I have also tried using the -d switch in lp to specify epson,  which 
also doesn't do squat (unknown).

This is kind of ridiculous.

Thanks again for any thoughts (think simple)

Marty.

PS is there some way I could copy the console to the serial port... Like 
in DOS copy con com1:?
