USER’S GUIDE

Horizontal 1200-dpi Image Format Mode(Raster Graphic Mode 1027)

The printer supports 1200 dpi printing for special image formats in 1200 dpi mode.

We recommend that the installed printer memory is 10 Mbytes or more for 1200 dpi printing.

To set 1200 dpi mode,

1.Set 1200 dpi printing mode by using the following PJL command: @PJL SET RAS1200MODE = ON

2.Choose PCL mode with the following PJL command:

@PJL ENTER LANGUAGE = PCL

(If you select a mode other than PCL mode, 1200 dpi printing mode cannot be selected.)

The PCL Mode set command for 1200 dpi Image Format is ESC *b1027M. The transfer raster data command (ESC*b###W) then transfers horizontal 1200 dpi data.

<1200 dpi Graphic Data Compression Format>

This compression format consists of blocks of data 64 dots down the page starting from the leading edge of the paper.

Ex.)	If the graphic data extends over three bands as shown in the
	following diagram, it transfers the data as three blocks of data:
	ESC*b##W <Block 1> <Block 2> <Block 3>
	0		Band 1
	64
		Block 1	Band 2
	128
		Block 2	Band 3
	192
		Block 3	Band 4
	256
			Band 5
	320

In mode 1027, the transfer graphic data command byte count does not have a limitation of 32,767 bytes.
