Digital BW, The Print

I have been able to install and get QTR to work over USB, but as of yet, not my network.  
I'm not sure if I am entering the correct IP address when the script calls for it.  Does 
anyong know if a way to get an epson 9600 correct IP address.  It works fine printing 
straight out of photoshop with the epson network drivers.  Any other common problems 
over networks.

I asked a related question yesterday but have not, as yet, received a 
response.

Could someone PLEASE explain what the Quadtone RIP needs a network 
for, how it uses the network, etc?   Thanks.   

Unlike some people, who have to use a loopback adapter, I actually 
HAVE a perfectly good network with a heterogeneous mix of Windows and 
Linux, but the PC I'll be running on is directly connected to my 
2200, so  don't understand how the network even factors into it.

Could someone please clarify this?

It by passes the driver and printer subsystem and prints to the raw
device.  This feature only exists in the command line, and the device
name is lptx (which represents a virtual port).  the only way to get
access to the raw device without writing a custom printer driver that
also controls I/O is to use the printer sharing feature of Windows
(all windows printer drivers support older dos style printing). 
Printer sharing requires a network to function.

If you have an exisitng network installed, all you have to do to take
advantage of QTR is to share your printer.  

I know that this is a bit cursory explanation but as someone who used
to write printer drivers I am impressed with the simple elegance that
Roy used to drive windows printers.

I simply want to use the network because the big printer is in
another room from the 
computer workstation, and already connected through network cabling
in the walls and a 
couple of gigabit switches.  It is close enough to connect via USB,
but not as clean with 
calbles on the floor going through doorways etc.  So, QTR doesn't
NEED a network, you 
can use USB.

No, that's not what we're talking about.   QTR, at least in Windoze,  
needs a network, or it needs to be faked into thinking that you're 
attached to a network.   That's why people running QTR who aren't on 
a real network, have to use a loopback adapter.

My Wasatch SoftRip uses a "text only" Windows printer driver to 
dump the data to the printer. That way it can rely on its own 
spooling and bypasses the Windows control on printers. I've 
mentioned that as an alternative for QTR to the network solution. 
So it could be done in another way. However Roy's solution has 
the nice advantage that the Epson driver still functions and can 
be used for all what QTR can't do.
