As I said before, this seems to work just fine with the
740. When I got it I tried both parallel and USB and
decided to just connect it via USB because it was working
exactly the same way regardless of the connection type
(and my cats used to knock out the parallel cable from
the back of my computer every now and then :-)
I just sent an email to my contact at EPSON to get more
information about this (no promises yet, they still have
some stuff that's only available under NDA). But I'm
still not really convinced that this should go into the
printer part of the USB driver. There are some commands
that survive a printer reset, maybe this is one of them.
Can somebody please test if it is sufficient to send the
init string from Beat's UPP file just once per session
and be able to print jobs without this string prepended?
If this is the case I guess we could handle these
init strings with the proposed firmware downloader:
Whenever the printer is connected or switched on a user
space daemon would recognize the new device and depending
on the device ID would send some stuff to the device.
In our case we would not even need a downloaded, cat
would do the job.
