Sounds simple ;-)
Is the E3 chipset generic for most of the primax scanners? I don't
know what differences between the 19200 and 9600 are, and netscape
crashes when I go to www.primax.nl to find out :-(
If most of the control commands are essentially high-level (and
remember, I know nothing about drivers so I may well not be talking
sense) then presumably the drivers have a lot in common. It would
seem like re-inventing the wheel to produce a new driver for each
scanner.
What help is Primax giving? I guess they aren't providing the source
code for their drivers - although I don't see why not. It sounds like
there's more to what you are trying to do than just adapting the
windows drivers to a linux system.
I see you already have a basic driver for some parallel scanners
working. How (in very basic terms) does it work? Does it give
basic configuration commands, tell the scanner to scan, then
interpret the output the scanner produces? Or is there more to it,
with some degree of cross-communication throughout the whole
process between the scanner and the computer?
Sorry, lots of questions, but I'm very curious.
Cheers,
Bryn
