USER'S GUIDE
Appendix–39
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
64
128
192
256
320
In mode 1027, the transfer graphic data command byte count does not
have a limitation of 32,767 bytes.
