(I don't have the printer in question near me so I mayt be slightly off in the way it is worded.)
I'm going through thousands of old photos and want to save the settings on the scanner to USB, jpg, 400x400, no correction... It is very time consuming to manually key in the setup each time I want to scan a few pictures.
How can I either change the defaults or create a named set of settings to use (for 4x6 or 5x7 photographs if possible)?
