[comp.lang.postscript] HP LaserJet Series III

kelvin@cs.iastate.edu (Kelvin Nilsen) (03/14/90)

I am considering the purchase of the new LaserJet Series III, and would
 like to hear opinions from people who have already purchased and/or 
 evaluated this printer.  Specifically, I am wondering:

	1. Does the "Resolution Enhancement Technology" really make a
		difference?  Can you tell the difference between graphics
		printed with Series II, and those printed with Series III?

	2. How fast does Adobe's Postscript interpreter run.  I'm guessing
		it would run approximately half as fast on CPU intensive
		tasks (scaling, rotations, font construction) as an Apple
		LaserWriter NTX based on CPU speeds.  Is my estimate
		valid, or have I oversimplified things?  

		Has anyone benchmarked it?
			... for a full page of text?  for graphics?

		Given sufficient memory (how much is necessary?), is the
		Postscript interpreter able to overlap printing of page N
		with formatting of page (N+1)?

	3. Are there any major shortcomings or design flaws that I should
		be aware of?

I will summarize the information I receive and mail it to those of you
 you express an interest, or will post to the news groups if sufficient
 interest is indicated.


Thanks

I have played with the LaserJet III.  It uses the same print engine as the II.
The main difference is the Formatter board.  It rolls in all the current 
commands available in PCL/IV and adds HP-GL/2.  

Postscript support for the LaserJet III is only available with the purchase
of an additional Cartridge.  2 MB of RAM is recommended for full page       
300x300 dot graphics.  I have used 1.5MB at 300x300 but the design was VERRY
simple.

The memory boards used in the III are not the same as used in the II.  DO not
by a II memory board and expect to use it in the III.
