I think this is an unfortunate double use of the word 'option', to
mean both options set in the config file to control the internal
behavior of the driver, and options you can set on the command line to
control the scanned images. I don't think the config file has the type
of control you are looking for.

Well, I gather you are an old unix hand, from your earlier mails- so
perhaps all you need is a shell script, or an alias:

alias scan="scanimage --resolution 200 -x=......."

then just call 'scan'.

"well, I stand up next to a mountain- and I chop it down with the edge
of my hand"
