I went through this with an Epson 750 a couple months ago and got this to
work (with a *lot* of help from this list, thanks all!) You need to send a
specific sequence of codes to the printer through the USB port before it
starts printing. I have attached a file with the required codes. I use a
print filter like:
#!/bin/bash
exec cat /var/spool/lpd/epson-raw/epson-usb-codes -
for printing from Windows machines through Samba (raw codes straight to the
printer), and I use the codes that Pam Roberts discovered (see the link that
Randy gave you) for Postscript stuff.
I have a feeling that the codes need to be sent only once, but it doesn't
seem to hurt to send them for each print job (or in the case of the
Postscript stuff, every page!).

Hi,
Most Epson Stylus printers don't do straight ASCII.
They don't have internal fonts, so you must use a
printer filter to print to them.
What you do have in /etc/printcap for /dev/usb/lp0?
Also, you could search the archives (linked from
www.linux-usb.org) for "epson" and may be able to
find some help.
Here's a link that may help you:
