Hey, good clarification! And good description of how all document-importing systems should be designed to allow the most flexible document capture.
I admit to ranting about Brother’s awful TWAIN support, which is extremely frustrating given the number of my customers who want to use, or *expect* to use, or have customers how own, Brother MFC’s. It ends up in my lap, and my customers laps, because they are commercial software vendors.
So over and over I have to explain, in person and on my website, that Brother MFCs can’t do ‘automated’ TWAIN scanning (where the user scans without having to interact with the scanner or its user interface) – you will get only the first or last page of the job.
“If you want to support Brother MFC’s with your application, you will have to put in a special mode that allows interactive scanning (where the scanner’s dialog is displayed) and you will have to specially detect Brother MFCs, or support your users to select this mode when needed.”
= trouble, expense, and tarnished reputation for my customers.
“Yes, I know they claim to be TWAIN compatible. Yes, I’m sorry you or your customer already bought one. Yes, I know it was a great price for a scanner with an ADF!!”
