PW - Pen width 

PW [

 ; width 

p

 ; pen 

• 

This command specifies the width of the pen. 

• 

Pen width can either be specified as a fixed width in millimeters ( the default ) or relative to the distance 
between the scaling points P1 and P2. 

• 

If a width of zero is specified the thinnest width possible ( 1 dot wide ) is set. 

• 

Metric widths are scaled by the ratio of the PCL picture frame to the HP-GL/2 plot size.  If the ratio for the 
two axes is different,  the smaller one is used.  If this is less than the thinnest width available then a width 
of 1 dot is selected. 

• 

If no pen number is specified the new width applies to both pens. 

• 

If a pen number other than 0  or 1 is specified the command is ignored. There are six pens in the 
specification. 

• 

If no parameters are specified the pen width defaults to either 0.35mm or 0.1% of the distance from P1 to P2 
according to the current width unit setting. 

• 

Pen width settings are n ot affected by a DF command. 

• 

Pen width does not set the width of the lines that make up the characters in a label. 

• 

A PW command remains in effect until another PW command is issued,  until a WU command is used  or 
until the printer is initialized with an IN command.

• 

This command defines a rectangular pattern which may be used to fill the area. 

• 

i

 is the index number of the pattern that is to be defined and must be in the range 1-8.  8 patterns can exist 

concurrently. 

• 

If used with an index parameter and no others,  the pattern is defined as a solid black fill. 

• 

w

 is the width in pixels of the pattern that is to be defined and must be in the range 1- 255. 

• 

h

 is the height in pixels of the pattern that is to be defined an must be in the range 1 - 255. 

• 

p

 stands for a pixel in the defined fill.  

p

 = 0 signifies a white pixel,  

p

>0 signifies a black pixel.  The number 

of pixels specified should equal the number of pixels in the fill pattern (

w,

h

).  The parameter defines 

successive pixels' colors from left to right,  top to bottom.  If you do not supply enough pixel parameters 
the trailing pixels default to white. 

• 

Use the FT command to select a fill type from those defined with the RF command. 

• 

Omitting parameters sets all raster fill patterns to solid fill.
