Print Options
Orientation
If you need to configure the printer settings, first switch to the
GL/2 emulation mode, then change the settings using the printer
driver, or the control panel menus.
Note:
Settings or data saved in the printer's RAM (such as downloaded fonts)
may be erased when you change the emulation mode.
GL Mode
Specifies whether the printer uses a direct emulation of the GL/2
plotter language, or the HP LaserJet 4 emulation of GL/2.
Scale
Specifies whether the output from the software is scaled. The scale
factor is based on the output paper size of the application.
Origin
Specifies whether the logical origin of the "plotter" is the corner
or the center of the paper.
Pen
Allows you to choose a pen which you can then set the thickness
for in the Pen 0 through 6 item. The LJ4GL2 mode supports two
pens (0 and 1), while the GLlike mode supports seven pens (0
through 6).
End
