6.1.4.

User-defined pattern command 

Esc*c#W [ data ] 

(27)(42)(99)#(87)  

<1Bh><2Ah><63h>#<57h> 



# should be in the range 0 ~ 32767. 



# stands for the number of pattern data bytes. 



User defined patterns can be defined by binary data or an 8 byte pattern descriptor. 



The formats for the pattern descriptor are listed below. 

<For 300 dpi> 

MSB 

      LSB 

0 - 1  Format (0) 

Continuation (0) 

2 - 3  Pixel Encoding (1) 

Reserved (0) 

4 - 5  Height in Pixels 

6 - 7  Width in Pixels 

8 -  Pattern Image 

MSB 

      LSB 

0 - 1  Format (20) 

Continuation (0) 

2 - 3  Pixel Encoding (1) 

Reserved (0) 

4 - 5  Height in Pixels 

6 - 7  Width in Pixels 

8 - 9  X resolution 

10 - 11  Y resolution 

X=Y: 300 or 600 

12 -  Pattern Image 



A pattern which is defined at 600 dpi cannot be converted to one at 300 dpi. 



Format - set to 0 or 20. 



Continuation - set to 0. 



Pixel Encoding - set to 1. 



Height in Pixels - specifies the pattern height by the number of rows. 



Width in Pixels - specifies the pattern width by the number of pixels. 



Pattern Image - consists of the raster data for the pattern. 



X resolution - specifies the resolution in the X scan direction. 



Y resolution - specifies the resolution in the Y scan direction. 

6.1.5.

Set pattern reference point 

Esc*p#R (27)(42)(112)#(82) 

<1Bh><2Ah><70h>#<52h> 



This command sets the pattern reference point to the current cursor position. 



# specifies whether the pattern rotates with the print direction or remains fixed. 



The Pattern reference point should be placed on a physical page and the base pattern is positioned at the 
pattern reference point for tiling.
