- Caveat: my experience is with non-Turbo systems only, your mileage may
- vary.
-
- Heavy printing will definitely slow up a NeXT, especially if it is
- bitmaps, most noticeable when printing faxes. However, I find that the
- average user doesn't usually notice if they are not located in sight
- of the printer. The usual printing mix is generally short documents
- with mixed text and graphics, longer, more complex documents may be
- more objectionable.
-
- More RAM always helps. There is a noticeable difference in speed
- between each of 8, 16, 32, and 64MB increments. My recommendation
- (worth exactly what you are paying for it) is to put (at least) 32MB
- in (at least) your print servers. Get as much RAM as you can afford,
- you will quickly get paid back with increased productivity (not so
- much by the improved speed but by the lower frustration factor).
-
- In deciding between ethernet-attached printers and NeXT-attached
- printers consider that you can locate the former virtually anywhere
- while the latter have to be within 15? feet of the attached computer.
- This is my pet peeve with NeXT's printing hardware. Perhaps I should
- take up Steve Jobs on his offer to personally wire me up a 40 ft.
- cable! ;-)
-
- Engine speed (17ppm vs. 8ppm) is not usually the limiting factor in
- determining PostScript printer performance. The PS rasterizer is
- almost always slower than the printing engine, sometimes much slower.
- You may find that the "high-end" QMS actually has lower throughput
- than the NeXT printers. This is heavily dependant on the content of
- the files you print. I will say that printer vendors are doing a
- better job of matching image processor and engine speeds than they
- used to but the best way to evaluate them is to have an actual
- in-house hands-on bakeoff.
-
- You may want to take into account the fact that four NeXT printers (or
- even two) provide greater redundancy and backup than does one
- network-attached printer.
-
- Finally, paper handling counts for a lot in the "real world." The NeXT
- printer does not have many options in this regard. The
- network-attached printers I have seen usually have multiple paper
- sources and higher capacity. Your application has to be able to take
- advantage of these features for them to be useful, of course.
-
- Good luck with your decision,
- Glen Foster
