[This is
preliminary documentation and subject to change.]
A language monitor
provides a full duplex communications path between the print spooler and
bidirectional printers that are capable of providing software-accessible status
information and adds printer control information, such as commands defined by a
printer job language, to the data stream.
PJLMon.dll supports
Printer Job Language (PJL) and provides bidirectional communication for PJL
printers.
Please refer to the DDK
documentation for more information about print monitors.
This sample runs on the x86 platform and is 64-bit compliant.
The code must be built
using the build environment shipped with the DDK. To build the sample, run build
from this directory. The DLL will be placed in the i386 platform directory.
To install a language
monitor, its file name must be listed in an .inf file by using a
LanguageMonitor entry. This entry must be included for every printer driver that
controls a printer requiring the use of the language monitor.
Once built, the sample
will produce four binaries: Pjlmon.dll, Pjlmon.lib (an export lib), Pjlmon.exp,
and, if the sample is built in a checked environment, Pjlmon.pdb.
