As with anything else, the answer is "depends on what you want to do with it." 5MB is plenty for 7/7 and a few documents. But you won't be able to also fit Lisa Pascal Workshop. Very cool. I asked because I wrote some code about 15 years ago to print and scan in barcodes. The application was to track incoming shipments, when a truck arrived. We'd scan in the inventory sheet with a high speed scanner (I think either the library or the scanner was called Kofax or something like that), then my app would assign a barcode ID and print a 2nd copy of the sheet with the barcode on top which was attached to the shipment. Then at every step the bar code was used to track it and people signed it or had someone with a barcode reader scan it in at every step the shipment was seen and had all the items inspected. At the end, once signed and all that, the barcoded page was rescanned in, and all the places and times the document showed up on as well as the first and last scan were stored. So that way if something "fell off the truck", it could be tracked to the last known scan. It was fairly easy to generate the bar codes and print'em out as HP PCL, but much harder to recognize them. I pulled a bunch of tricks and eventually got it to work well enough to be useful. I remember using Code 3 of 9, and having worked it on nothing else but this thing for several weeks, I could read the numeric symbols + start/end just by eye. (I've forgotten them since.) :-)
