This is the parallel printer port base device driver for OS/2.
- TIP
- With Warp, the default transmission protocol used by PRINTO1.SYS and PRINTO2.SYS is the polling transmission method. The protocol used by previous versions of OS/2 was the interrupt transmission method. In Warp, you can change back to the interrupt method by adding the /IRQ parameter.
- TIP
- From Paul Kurr: "Since I'm running on a LAN at work here, I have no need for direct printer support of any kind since this is taken care of by my NOS (LAN Server). So I have REM'd BASEDEV=PRINT01.SYS to save some RAM."
- Note
- This is one of the critical drivers for the OS/2 Kernel.

CONFIG.SYS Statement
Provides support for parallel ports LPT1, LPT2 and LPT3 on PCs with EISA/ISA or PCI buses.
BASEDEV=PRINT01.SYS <parameter>
- Parameter
- /IRQ - Changes the transmission method from polling to interrupt. The interrupt method is faster but won't work on every system.
The used IRQ depends on the I/O address the LPT port uses. IRQ 5 is used on LPT ports installed on the I/O address 278, IRQ 7 is used on LPT ports installed on the I/O address 378 or 3BC. To find out the I/O address of a LPT port use the Hardware Manager.
- /SHR - This parameter in conjunction with /IRQ parameter directs the PP DD to service PCI IRQs as shared.
- NOTE
- If your printer (for example, old dot matrix printer) generates IRQs without setting interrupt pending (occurred) bit in PCI PP status register correctly then you cannot use PCI IRQ sharing and must not use /SHR parameter.
- /TOU:ddd - Specifies maximum wait time in seconds before cancelling the print request. This is a 3 decimal digit value (by default - 120 seconds).
- /F - Find parallel ports on PCI combo (serial/parallel) cards automatically.
- /MPL - modifies polling procedure - makes it less processor resource consuming by scheduling other systems tasks at certain print points, may decrease print speed.
