[comp.laser-printers] Higher Resolution Laser Printers?

forrest@blia.UUCP (Jon Forrest) (04/21/87)

Most of the recent discussion of future laser printers has been
about faster printers or new PDL's. I'm interested in higher
resolution laser printers. The fact that 300dpi printers have been
around so long seems contrary to the normal technological improvements
we have seen in memory capacity and microprocessor speed.
Perhaps the lack of higher resolution printers is due to the fact
that they will require lots of memory for holding bit maps but again,
memory prices and capacities are going down much faster than laser
printer resolution has gone up.

There are rumors that Apple is coming out with a 600dpi printer. Which
engine will they use?

 AMI-Varityper already offers a postscript 600DPI laser printer.  It
 comes with a switchable interface so that you can hook up 
 Centronics parallel, Serial, and Apple-talk (at least those, I don't
 know what else besides).

 Check with Varityper at 11 Mt. Pleasant Ave.

There are a few higher resolution laser printers. Data Recording Systems
has a 800x800 bpi unit, PrintWare has a 1200x600 bpi unit etc. Higher
resolution will bring better typography but sooner of later the marking
process comes into the picture. Laser Phototypesetters and Imagesetters
on photographic materials operate as high as 2540 bpi. These units do
NOT print on xerographic engines, however. I assume from your question
that you were looking for laser xerographic printers like the DRS and
PrintWare units. Halftones still leave something to be desired due to
the particle size of the toner.

AM International's Varityper division has released the VT600 600 dpi
PostScript printer. Will see it May 21 or 22. Will comment.
