Probably some type of multi-row sensor enable command. You could certainly send this command only in the case of 600dpi. > 2.

The machine might have some limited granularity to the -x and -y values, like rows must end on 64 byte boundary, or 32 pixel boundary, or any number of weird problems :) > 4.

See the sane standard regarding option constraints. You probably currently have a RANGE constraint, but you have other choices. > > I won't have much time in the next couple of weeks to work on the code. > Tomorrow is the last "free" day where I can do something.

If not, compress it and send to the list. allan PS- Please join the list so I don't have to keep approving your posts. -- "The truth is an offense, but not a sin"
