OS2DD306 - Printer Device Drivers

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)

Length

 * 5 days
