Merge Control Command (HP-GL/2)

Merge Control Command (HP-GL/2)

The Merge Control (MC) command specifies the raster operation (ROP’s) to be performed in HP-GL/2. Raster Operations specify how source, destination, and patterns are combined to produce final images. This command supports all 256 Microsoft Windows ternary (ROP3) raster-operation codes.

0= opcode value is ignored; printer sets ROP to 252.

1= opcode value is used as the ROP value. If no opcode value is sent, printer sets ROP to 168. If opcode is out of range (some value other then

0-255), the command is ignored and the default ROP of 252 is used. (For example: MC1,60; MC1,60-; MC1,+60; MC1,60+; all set the ROP to 60; however, MC1,-60;or MC1,300; set the ROP to the default value (252).

Notes This command is the HP-GL/2 version of the PCL Logical Operation command.

This command sets a ROP value which affects not only

HP-GL/2 operation but also the PCL ROP value.

The MC command is defaulted by an IN command.
