I keep a super-sized Mustek A3 1200 USB scanner around for big scanning jobs. Its antiquated driver works fine in Windows XP, but when I want to use it on my Macbook, I had to virtualize Windows just to scan (Mustek’s drivers are ancient). Tonight I discovered that while the TWAIN driver for Photoshop CS4 doesn’t see the scanner when run as a native Intel application, if I check the “Open using Rosetta” box in Photoshop’s properties then run the application, the A3 1200 USB is sitting there happily in my Import/Export list. Life is happiness indeed. No stitching together partial-page scans for me!

Of couse, now I wonder if I could have been doing this all along, and I merely stumbled upon it while configuring CS4.
