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

Stroke weight

 

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

polygons can form one polygon.

A set of up to sixteen vertical tab stops.  Up to eight vertical tab channels can be set 
up in the Epson FX-850 mode.

performed.  To use the font again you must download it 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.
