OS/2 PM Printer Device Driver - Course OS2DD306
  OS/2 1.x/2.0 Presentation Manager Printer device driver

Objective
======================
    To expedite Independent Hardware Vendors (IHV) support of OS/2 2.1 by
writing Presentation Manager Device Drivers (PM DD) to support various
Printers
    This class will cover the core PM DD modules used to interface OS/2
applications and print spooler to the printer; this will include
support for WIN and GPI calls.  Interfacing to the graphics engine and
DISPLAY.DLL will be covered in detail.

Target audience
======================
IBM or IHV programmers who code GUI device drivers for printers.

Attendee prerequisites
======================
   a. Programming expertise: C, MASM
   b. Intimate knowledge of IHV hardware & programming protocol
   c. Other device drivers for IHV hardware (i.e. printer drivers)
   d. Purchased development software (OS/2 2.1, DDK, MSC 6.0, MASM 5.1)
