I have a little Neat Receipts Travel Scanner that I originally bought for my Windows netbook when I'm travelling. It's so cute I wish I could use it on my Mac ... and not under VMWare or BootCamp.
Neat Receipts would sell me their bloatware for the Mac for $80. I looked for a cheaper option... My favorite, VueScan, unfortunately doesn't work with it.
Then, I saw a forum post that said that the Neat Receipts was actually a rebadged PlusTek M12 scanner. I went to their website and downloaded their M12 installer for the Mac (PlustekM12Series.dmg BETA dated 7/2010), clicked on the installer and ... the installer crashed with a Rosetta error, of all things.
On a hunch, I opened up the installation package (right click on it and select "Show Package Contents") and found inside it two other sub-installation packages (opticslimM12Digiscan.pkg and opticslimM12Support.pkg).
I installed those two installes one-by-one and rebooted, and presto, my Neat Receipts scanner works just fine as a PDF or JPG/PNG/TIF scanner under Mac OSX natively using the DigiScan application. Yippeee!
Here's a scan I made from a magazine article.
