I have a scanner (part of an HP PSC 1315 multifunction printer, if that makes any difference). I've recently paved my Windows XP machine and appear to have lost the software for the printer. This has meant that I have to use Windows Image Acquisition or Microsoft Word to scan images and documents.
The main problem that I have with this scenario is that WIA only scans to images, not to PDF, and I would prefer to have my documents scanned to PDF (the HP software scanned to PDF and did OCR as well). I haven't actually used the Word integration (as I'd prefer not to have Word fully installed), but I'm open to using it if it can help me. I have Word 2002/XP available.
I'm not really interested in finding a solution enough to have to buy something.
So, are there any free utilities for Windows XP which will let me scan to PDF? Extra points for OCR, great software, or ease of use.
