This is the better way to do it, given those two options, but I'm not
certain that I agree with you.  (Setting an input filter is even more of a
cheesy hack than putting this code in the printer driver, IMO.)

Since this string does appear in the Windows driver ouptut, it seems
that the Epson engineers felt the need to include it in every print
job rather than having it sent as Windows configures its USB devices
at boot/insertion.  They apparently didn't think it was such a bad thing
to do.  I'm inclined to agree.  It's just a few bytes and it guarentees
that the device will work.  I don't know why the printer has the behavior
of not listening to jobs from the USB port without that string anyway.

And why would you want two different queues going to the same printer?
