PW - Pen width 

PW [

]] [;] 

w

 ; 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 not 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.
