Version 1.1

    New features and enchancements:

	   - There was a bug that caused lines longer then 80 or 90
	     characters to crach the machine.  This has been fixed.

	  - Parallel Postscript printers can now be used. Version 1.0
	    always assumed the a Postscript printer was serial, it
		just ignored the preferences setting.  This version does
		not.  However, this must be specified before the device
		is open.  Once it is open, it can not be changed.

	  - Non-printable characters are mapped into the special
	    postscript characters.

Version 1.0

Text Support

The current AMIGA printer commands and ESCAPE sequences supported
include line spacing, pitch, normal, bold, underlining, italics, the
left margin, page length (in lines), and NLQ mode.  NLQ mode switches
between the Courier and Times Roman fonts (so does DRAFT/LETTER mode).


Raster Dumps

Currently 16 shades of gray form most pictures.  The only exceptions are
HAMs which use 256 shades, and "Black and White" mode which uses 2 shades.
White is represented as the lightest color of gray except in the "Black
and White" mode.  The margins and page size in lines define the maximum
print area.  I think all of the different special modes are supported
but I don't think they all have been tested.  SPECIAL_ASPECT is supported
but I was surprised that it does not seem to be used very much.  I have
tried printing from PAGESETTER (treating the LASERWRITER as a normal
printer), GRABBIT (you have to use SIDEWAYS print), and DELUXE PAINT.


General

Raster dumps are treated like text when it comes to page boundaries.
In other words, if a raster dump will not fit on the current page
it is moved to the next page.  When the printer device is closed the
last page is ejected if there is text on it.  The CMD_FLUSH used by
DELUXE PAINT to abort raster dumps does not loose memory like the real
printer device.  The EXPUNGE call does not do any thing right now.
