I don't know exactly what is causing your problem but, considering the
process of elemination I'll tell you this :
I also have exactly the same printer running on USB since Sept of last year.
I have not had a single problem with it, text or photo. I'm using Red Hat 7.1
with a 2.4.6 kernel. I don't think it has anything to do with the USB
interface within the printer.
Good Luck
Larry
