Internal font A font that is stored in the printer ROM and is therefore always available for
use, for example, Brougham 10 pitch, or a font generated from a scalable
typeface stored in the printer's ROM, for example, Tennessee bold 15 pt.
Isotropic scaling A form of image scaling using the SC command in HP-GL or HP-GL/2 mode
in which the user units must be of equal size. Hence it may not be possible to
use the entire graphics window to display the image.
Justification The way in which text is aligned. For example, left justification involves
aligning the left end of every line of text.
Label A text string that forms part of an HP-GL and HP-GL/2 plot.
Landscape The orientation in which the top edge of the page is longer than the side edges.
Logical page The area of the physical page on which the cursor can be positioned in
LaserJet mode. You can use PCL commands to specify the position of the
logical page on the physical page. Also known as the PCL addressable area.
LSB i) The least significant byte of a set of data bytes.
ii) The least significant bit of a single byte of data.
Macro A sequence of PCL commands that can be stored in the printer memory. To
run the sequence you need only use a single PCL command.
Macro execution Executing a macro is a way of running a macro whereby any changes made to
the modified print environment by the macro are retained when macro
execution has been completed.
Macro overlay environment Used only by a macro that has been enabled for overlay. A combination of
the user default environment and the modified print environment.
Medium The line thickness of normal type.
Modified print environment The collection of all current LaserJet printer settings. This environment is
saved if you call a macro or enter HP-GL and HP-GL/2 mode, and then
restored when the macro has finished running or when you quit HP-GL or
HP-GL/2 mode.
Monospacing Some bitmap fonts are printed with each character occupying the same space
on a line of text. This is known as monospacing.
MSB i) The most significant byte of a set of data bytes.
ii) The most significant bit of a single byte of data.
Pattern i) The hatching or cross-hatching that can be applied to an outline shape.
ii) The non-white areas of the source image in the LaserJet print model.
Pattern transparency The patterned ( non-white ) areas of the source image are either transparent,
in which case the destination image is visible through the white parts of the
pattern, or opaque, in which case the destination image is not visible at all
throughout the patterned areas of the source image.
PCL Printer Control Language. The language consisting of escape sequences that
is used to control the printer in LaserJet mode
