OSCPRPOL - HOW TO DISABLE POLLING FOR PRINTING IN OS/2 WARP
01/05/96
=======================================================================
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.
