Soft clip limits

See graphics window.  The soft limits are determined by the IW command. 

Source image

The graphic image that is applied to the destination image in the LaserJet print 
model.  The interaction of the two images is determined by the current source and 
pattern transparency settings. 

Source transparency

The source image is either transparent,  in which case the destination image is 
visible throughout the white parts of the source image,  or opaque, in which case 
the destination image is not visible at all through the source image. 

Spacing

The way in which a font's characters are arranged on a line of text.  See 
monospacing and proportional spacing. 

Stick font

The default HP-GL and HP-GL/2 font consisting of thin lined characters. 

Stroke weight

The thickness of the lines that comprise the characters in a particular font.  
Medium, bold and light stroke weights are commonly used. 

Sub-polygon

A shape consisting of a closed group of points connected by lines.  Several sub-
polygons can form one polygon. 

Symbol set

up in the Epson FX-850 mode. 

Temporary font

A downloaded font that is erased from the printer's memory when a printer reset is 
performed.  To use the font again you must download it again. 

Temporary macro

A macro that is erased from the printer's memory when a reset is performed.  If you 
want to use the macro again you must redefine it and download it to the printer 
again.

User default environment

The current combination of LaserJet factory default settings and settings made 
using the control panel.  This is the environment that is in effect when you switch 
on the printer in LaserJet mode or change to LaserJet emulation from another 
emulation mode.  You can reset the printer to its user default settings either by 
using a printer command or using the control panel. 

User units

Coordinate units specified by the user with the HP-GL and HP-GL/2 SC command. 

Vector graphics

A method of defining graphic images in terms of coordinates,  points and lines.  
The HP-GL and HP-GL/2 graphics languages use this method.
