(HP71B) Where to get the best quality SW IDS prints?

[brouhaha]

When I scanned the the IDS originals I had (71 SW vols I, II, III, 71 HW, and HP-IL), I scanned them at 600 dpi on a ScanJet 3c, and used a simple script on Linux to de-up the 2-up and 4-up pages (vol II and III). It worked very well and with very little manual effort because the sheet feeder on the scanner ensured that none of the pages had any significant angular skew, and that there was almost no variation in the image positioning. These are the scans on the MoHPC discs.
