Hi Stan,

> Yes, IP has it's own driver.

Does it "invoke" the Epson driver, like the Piezo "driver" does?

Knowing what we "believe" we know about resampling to 720, it is very
possible the Cone Piezo driver actually does just that...and still uses the
Epson driver, but just sends it pre-resampled four ink data.  It's not
actually a "driver".

I'm not sure there are any "OS print routines" (except spooling).  I think
that there is a standard API to the printer driver, and the driver
communicates with the printer thorough the OS, but only using it as a port
manager, like USB, parallel, serial...I don't believe the port management
function has any printer specific (or limiting) stuff in it.

I've written a printer "driver" routine to do alignment on the 3000, and it
calls only I/O routines to send Epson specific commands to the parallel
port.  Any limitation on page length exists only in the printer it
self...not in the I/O calls.  There may be something different for spooling,
which I have never done.
