[comp.windows.ms] LaserWriters and Windows 3.0

There seems to be a lot of confusion about Apple Laser printers.
 
 It has been said:

Basically the PostScript LaserWriters are the old NT and NTX, and the
newer Personal LaserWriter NT (4ppm). These are poor value for
money and will be replaced in June.
 
The latest LaserWriter is the LS and it is much cheaper as it does
not have PostScript. In fact it doesn't have anything - it does
scalable fonts but these are imaged in the Macintosh ie. TrueType
sits in the computer not in the Printer. Likewise drawings are
imaged by Quickdraw in the Macintosh and the 300 dpi image sent
to the printer.
 
It is a bit more clever than it sounds as the driver has in-built
compression and the page image is decompressed in the printer, so
it only needs 512K RAM, it uses a serial port running at almost
1 Megabaud thro some trickery.
 
When windows can support TrueType it can use the LS, or in fact any
other printer without PostScript.

P.S. I have no attachment to any vendor, I've just been printer
shopping lately.
