TWAIN Drivers on Mac I'm primarily a Windows admin, but I just got a new MacBook Air with Lion on it. I'm trying to use it with my Brother MFC-7820N printer/scanner/fax device.

I've installed drivers, and am able to both print and scan, BUT not via TWAIN (applications such as Image Capture and Preview do not show the scanner as a valid source for importing documents).

I've downloaded the TWAIN driver. It says it installs, but doesn't prompt me to do anything (like enter the IP address of my scanner) after installing. Arrgh.

Being so new to Lion, and somewhat new to Mac OS (relative to my 15 years as a Windows admin), I'd love some advice on how TWAIN works on Mac OS. I'd also love to know some of the popular newsgroups or places to submit this question.
Hamrick VueScan

This is a "Swiss-Army-knife" scanning application that supports hundreds and hundreds of makes and models of scanners, even many obsolete ones which don't have direct Mac OS X support. 

Download and evaluate the trial version. 

I use it with my Brother MFC-6490CW, which does have Mac OS X drivers, but I'd rather use VueScan than use the Brother or Apple scanning software. Although VueScan has TWAIN support, I use it as a stand-alone scanning solution to output PDF, TIFF and JPEG.
