3. Emulation Switch
Emulation setting can be switched between automatic emulation
sensing (switching) and fixed emulation modes as shown below.

Emulation switching is performed in the following manner.

In the automatic emulation sensing mode, for print data without the
PJL command, the emulation is automatically switched either to Post-
Script, to PCL5e based on data sensed. In other words, automatic
emulation sensing (switching) is available only between PostScript
and PCL5e. For print data with the PJL command, the emulation is
automatically switched to the specified one with out sensing the data.
When print data without the PJL command fails to be sensed, or
when the print data is given the PJL command but the specified
emulation is not present, the data is handled in the PCL emulation.
In the fixed emulation mode, for print data without the PJL command,
the fixed emulation is used to handle the print data.Print data with the
PJL command is switched to the specified emulation. When print data
is given the PJL command but the specified emulation is not present,
the data is processed by the default emulation.
The PJL Enter command specifies PostScript and PCL5e.
4. Resolution
The printer controller supports only 600-dpi binary images in single bit
per pixel mode. The print engine does not support resolution settings
other than 600 dpi (fixed at 600 dpi). When300 dpi is specified for
resolution, 4 pixels are represented as 1 dot to create 300dpi image.
In other words, the printer controller always sends 600-dpi images to
the engine.
5. Font

The job control commands support PJL (Printer Job Language) which
HP printers include. PJL is available for all emulations (PCL5e,Post-
Script).
7. Host I/O Port Selection
There are two host I/O ports, the P1284 port and the Network(NIC)
port, as described before. The host I/O port can be selected between
the I/O port automatic port switching and the I/O fixed port setting.
The automatic port switching has two settings, between jobs and after
I/O time-out.
