Once in Raster Graphics Mode, PCL commands and text imply an End Raster Graphics (EC*rC) except for the following commands:

zTransfer Raster Data

zSet Raster Compression Method

zRaster Y Offset

In addition, the following commands are ignored (i.e., locked out) while in Raster Graphics Mode and do not imply an End Raster Graphics command:

 

z

Start Raster Graphics

 

z

Set Raster Width

 

z

Set Raster Height

 

z Set Raster Presentation Mode

 

z Set Raster Graphics Resolution

 

 

Notes

An implied End Raster Graphics resets the Raster Compression

 

Method 3 seed row, but does not reset the Raster Compression

 

Method nor the left raster graphics margin.

If source and/or transparency modes have been set, frequent start/end graphics commands in an image can result in a memory overflow condition.

Raster Y Offset Command

The Raster Y Offset command moves the cursor position vertically the specified number of raster lines from the current raster position in the raster area.

EC * b # Y

#=Number of raster lines of vertical movement

Default

=

N/A

Range

=

0 - 32767

This command is recognized only while in raster graphics mode and only within the raster area.
