v
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,  it is  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 
 
PCL addressable area  See logical page. 
 
PCL picture frame  See picture frame. 
 
Pen  Although this printer is a laser printer the HP-GL/2 and HP-GL graphics languages 
retains the notion of a pen and allows you to select between two pens,  white and 
black.  You must select a pen before you can draw anything.  The HP-GL and HP-
GL/2 language were originally developed for use with plotters and the terminology 
remains.
