PRINTER.SYS
Support for code page switching on IBM printers
See also <CHCP> <NLSFUNC> <DEVICE> <CONFIG.SYS>
This is a device driver to support code page switching on certain
types of printers. Printers supported are Proprinter Model 4201 and
IBM Quietwriter III Printer Model 5202.
USE: DEVICE=[d:][path][PRINTER.SYS LPT#[:] = (type[,[hwcp[,...]][,n]])
LPT# specifies the printer device and can be entered up to three
times, one for printers LPT1, LPT2, and LPT3. The device name PRN
may be used in place of LPT1.
type specifies one of the following printer types:
4201 - IBM Proprinter Model 4201 or 4202 XL
5202 - IBM Quietwriter III Model 5202
4208 - IBM 4207 or 4208, Proprinter X24 or XL24
hwcp specifies the code page image built into the hardware (437, 850, 860,
863, or 865). For some printers multiple code pages may be
specified. For the IBM Quietwriter III Model 5202, the hwcp can be
one code page, such as 437, or it can be a pair of code pages, such
as (437,850). For the IBM Quietwriter III Model 5202, if two hardware
code pages have been specified, then no code pages can be prepared,
and the value of n must equal zero.
n specifies the number of additional code pages that can be prepared.
The value of n determines the number of buffers PRINTER.SYS will set
up to hold code pages being prepared. The maximum number of code
pages that can be prepared is 12. This figure is dependant on the
printer hardware
EXAMPLE: DEVICE=PRINTER.SYS LPT1:= (4201, 437, 1) LPT2:=(5202, 437, 0)
This example installs the code page switching for the LPT1: and LPT2:
devices. It instructs the LPT1: driver that the printer is a IBM
Proprinter Model 4201 and the LPT2: driver that the printer is an IBM
Quietwriter III Model 5202. Both printers have the 437 code page
built in. The LPT1: driver is able to hold one code page prepared by
the MODE command, while the LPT2: driver can have one code page
prepared.
