Epson LX-300 printing margins off

Archived from groups: comp.periphs.printers (More info?)

I am using a generic/text only driver for a Epson LX-300 printer and
the text margins appear to exagerate hosizontally and the text also
appears slightly big, this is on a Windows XP machine. I had the same
printer and same driver installed on a Windows 95 machine and all was
printing fine.

What I am printing are cheques, and the entries need to be in the
correct fields on the cheque. I have copied the same settings in the
font selection section and also in the 'begin print job' printer
commands. I dont know what else is causing this? any suggestions would
be great.
