NAME

lp − line printer

SYNOPSIS

For the IBM RT PC:
device lp0 at iocc0 csr 0xf00003bc priority 7
device lp1 at iocc0 csr 0xf0000378 priority 7
device lp2 at iocc0 csr 0xf0000278 priority 5

For the IBM 6152 Academic System:
device lp0 at iocc0 csr 0x000003bc priority 7

DESCRIPTION

Lp provides the interface to the IBM 5152 Graphics Printer and the IBM 4201 Proprinter using the parallel port of the monochrome adapter or PC/AT serial/parallel adapter (for the IBM RT PC), or the planar parallel port of the PS/2 Model 60.  Bytes are sent to the printer as is; the driver does no interpretation.  No automatic page-ejects are generated; this can be done by the print spooling system.  See “Line Printer Spooler Manual” in 4.3BSD UNIX System Manager’s Manual. 

The IBM 4201 Proprinter switch settings should be as follows:
  switches 3,4,7 off
switch 6on
switch 1,2,5optional - See IBM 4201 Proprinter Guide to Operations,
PN6328945, for effects of these switches
 

Although a priority must be specified in a configuration entry, the driver does not currently use interrupts on the IBM 6152 Academic System. 

The unit number of the printer is specified by the minor device divided by 8.  Currently, the low three bits are ignored.

DIAGNOSTICS

lp%d: offline. 

lp%d: out of paper. 

lp%d: unknown printer error, status = 0x%b.  The printer did not become ready in 20 seconds, for some reason other than being off-line or out of paper.
