• 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.

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.
