           How to Disable Polling for Printing in OS/2 Warp
=======================================================================

Please Read Entire Document for Full Explanation of Procedure
-------------------------------------------------------------

DESCRIPTION

* Printing is slower than in OS/2 2.1, OS/2 2.11, or OS/2 for Windows.

* Printing is interrupted by other processes when multitasking.

* Printing uses excessive CPU resources, as shown in the Pulse utility
  program.

  Note: This might occur in non-Micro-Channel systems.

RESOLUTION

OS/2 Warp defaults to polling for printing, rather than using IRQ 
settings as in OS/2 2.1, OS/2 2.11, and OS/2 for Windows.

To change printing to IRQ 7 for LPT1, and IRQ 5 for LPT2:

1. At an OS/2 command prompt, type E CONFIG.SYS and press Enter.

2. Find the BASEDEV=PRINT01.SYS statement and change it to:

      BASEDEV=PRINT01.SYS /IRQ

The / flag disables polling and enables IRQ7 for LPT1, and IRQ5 for 
LPT2.
