AccXES PJL Interface
3 HP-PJL Commands
This section defines the HP-PJL commands that are utilized by the AccXES software architecture as
well as the custom commands defined by the AccXES architecture. A user job with custom AccXES
HP-PJL commands embedded within it is required to run without error on a standard HP-PJL printer.
In practice, this means that new HP-PJL commands are embedded within the HP-PJL COMMENT
command.
Conversely, standard HP-PJL jobs should run without error, albeit with loss of printer feature control,
on a AccXES printer. Consequently, all HP-PJL commands defined in [HP96] are implemented in
AccXES printers. The AccXES printer will most closely resemble a Hewlett-Packard LaserJet 4V/4MV
printer in its HP-PJL implementation.
3.1 Kernel Commands
The kernel commands detailed in the following sections are implemented in the AccXES printer.
3.1.1 UEL
The UEL command will be implemented as defined on page 4-2 of [HP96]. From the HP-PJL
specification, it is defined to be the following character sequence:
<ESC>%-12345X
3.1.2 ENTER
This command is implemented as defined on page 4-4 of [HP-PJL]. The possible values to be taken by
the LANGUAGE parameter are:
•
AUTO
•
CALCOMP
•
CALS1
•
CALS2
•
VDS
•
VCGL
•
C4
•
CGM
•
VRASTER
•
HPGL2 {Alternately, HP-GL/2}
•
