PJL overview
The printer job language (PJL) is an integral part of configuration, in addition to the standard printer
command language (PCL). With standard cabling, the product can use PJL to perform a variety of functions
such as these:
●
Two-way communication with the host computer through a network connection or a USB connection.
The product can inform the host about such things as the control-panel settings, and the control-panel
settings can be changed from the host.
●
Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O. The
product can receive data from more than one I/O simultaneously, until the I/O buffer is full. This can
occur even when the product is offline.
●
Context-sensitive switching. The product can automatically recognize the personality (PS or PCL) of
each job and configure itself to serve that personality.
●
Isolation of print environment settings from one print job to the next. For example, if a print job is sent
to the product in landscape mode, the subsequent print jobs print in landscape mode only if they are
formatted for landscape printing.
PML
The printer management language (PML) allows remote configuration and status monitoring through the I/O
ports.
LEDM overview
NOTE: HP LaserJet Pro M201/M202 Printer series
The low-end data model (LEDM) provides one consistent data representation method and defines the
dynamic and capabilities tickets shared between clients and devices, as well as the access protocol, event,
security, and discovery methods.
