Function 69

Prints the specified NV graphics data. 

112 

GS ( L pL pH m fn a bx by c 
xL xH yL yH d1...dk 

Function 112

Stores the raster graphics data in the 
print buffer memory. 

▪

 pL, pH specifies (pL + pH x 256) as the number of bytes after pH(m, fn, 

and [parameter]). 

▪

 Frequent write command executions by this command may damage the 

NV memory. Therefore, it is recommended to write to the NV memory no 

more than 10times a day. 

▪

 While processing this command, the printer is BUSY while writing data to 

the NV graphics memory and stops receiving data. Therefore it is prohibited 

to transmit data including the real-time commands during the execution of 

this command.
