Read_Me file for IBM printers.
------------------------------

The "IBM.Pro-X24E" printer definition file uses features which mean it will
not work on some of the early IBM printers. It uses ESC "[g" graphics
commands to perform 24 pin dumps, ESC "d" to perform leading zero
suppression and ESC "[\" to switch the vertical units to 1/180 inch instead
of 1/216 inch. The use of these codes for the graphics resolutions means
that this printer definition file will not work with the IBM Graphics
Printer, Proprinter, Proprinter II and Proprinter XL. ISO Latin 1 text
printing uses ESC "[T" to switch to code page 850 (Multilingual) which
allows accurate text printing of almost all ISO Latin 1 characters.

If you have a very new IBM compatible printer which can do 48 pin graphics
using ESC "[g", you may be able to use the "Canon.BubbleJet" printer
definition file. This is the same as the "IBM.Pro-X24E" file except that it
provides 360 DPI vertical resolution graphics modes (non interlaced) and the
360 DPI horizontal definitions are non interlaced.  

The "IBM.4019/17" and "IBM.4019/39" printer definition files are for the IBM
LaserPrinter (PostScript), containing 17 fonts and 39 fonts respectively.

The "IBM.4216" printer definition file is for the IBM Personal Pageprinter
(PostScript).
