Scan Documents Into Your Mac with an All-In-One Printer/Scanner/Fax
I use the Epson Workforce 600 for my office print/scan/fax needs, see my brief review in An inexpensive and fast everyday office printer.
One thing I do regularly is to scan a variety of receipts, snippets of articles, etc.
The Epson Workforce 630 (about $120 @AMAZON) can scan directly to a digital camera SDHC or Compact Flash memory card, which is the way I worked it until I got tired of transferring the card to/from the scanner/computer each time. Also, the direct scan to card approach does not offer TIF output, so for highest quality, scanning to the computer is better.
But the Epson Workforce can also scan directly to the computer, as shown below.
Scan directly into your Mac using the Mac OS X Image Capture application, as shown below.
