BTW, it us worthwhile to point out that the 50 ppd value is NOT based on the
speed of the printer, but, as Kevin points out, consideration of average use
in order to make reasonable estimates of warranty repair costs per annum,
etc. If the printer were continously printing, it can print far more than 50
pages in one day. The Dwskwriter for that matter is also quite a bit faster
than the DeskJet, due to the improved driver and data compression. So the
guy with the PhD dissertation would be able to print out his 200 pages without
waiting 3 days.

Hey Vancouver (maybe Kevin), could you post the # of ppd for 1) DeskJet and
2) DeskWriter if either of these printer were confronted with continuous
printing?
