I haven't tried Vuescan but using SimpleScan and xsane the scans from my old (but still fully functional) HP Scanjet 4400c exhibit a lot of variation in colour cast - even between consecutive scans of the same document. I assume that the HP scanning software has some way of checking the colour balance on each scan as it gives very little, if any, variation. The only way that I have found to use it reliably is with W2K (yes the scanner is that old) installed under VirtualBox and the HP software installed under W2K - a bit of a pain but the results are worth it.
Tried simple scan yesterday and it's a really efficient way to scan docs directly to a PDF(*), but does it work as a scanner for Gimp?
There is a huge variation in file size when converting an document to PDF, depending on application used. Possibly some compression setting for embedded JPEGs, but Gimp doesn't see to allow tweaking this.
PS: SimpleScan saves documents at 100PPI, which is the default setting when loading PDFs in Gimp. Coincidence?
