I had a IIIP at one time and loved it. It was a real workhorse, but I had
to replace it about a year ago. However, I used to print booklets with it
and did not need a special driver. This can be achieved with certain
software. Ed Rufs mentioned Clickbooks, which I used for awhile. I could
achieve the same results with settings within WordPerfect, and I am sure
other software could do the same thing.
