Hi Sane folks,

I'm the project lead for Gutenprint (printer drivers).  We have a user
who's having trouble using Gutenprint with the Epson RX685 using its
OEM driver on Macintosh OS X; should we recommend that people use Sane
on OS X with this printer (and other similar printers) in conjunction
with Gutenprint?  Is there any special advice we should give them in
this regard?  Does scanning work over a network in the kind of
configuration outlined below?

I have an RX580 that works fine with Sane (on Linux); unfortunately,
our OS X expert doesn't have one of these multi-function devices.

(If you have issues with people using Sane with OEM printer drivers
installed, perhaps you might want to point them at Gutenprint.)

Unfortunately, there is no one perfect solution.  If you keep the 
Epson rx685 on the print server, you will have to choose whether you 
want to use it as a scanner or a printer and only have the 
appropriate software installed.

The other choice is to attach the Epson rx685 directly to a Mac 
computer via USB and use only the Epson supplied software for the 
printer and the scanner.  I think you will be able to have other 
computers share the device without problems.  That does mean, 
however, that the Mac the rx685 is connected to must be turned on and 
awake for other computers to access the device.

Regardless of where or how you insert the multifunction machine in 
your network, you cannot use the Gutenprint drivers along with the 
Epson Scan software.

I should note that this is a common problem we see with multifunction 
devices -- at least in Mac OS X.  Part of the problem is the "nature 
of the beast".  The other part of the problem is that most 
manufacturers  write printer drivers that only work when the device 
is directly connected to the Mac computer via USB.
