6.22 Enter TIFF compressed mode “ESC . 2 v h 1 0 0”
Format:
ASCII ESC . 2 v h 01H 00H 00H
Hex 1B 2E 32 v h 01 00 00
Decimal 27 46 50 v h 1 0 0
Range of Values for Parameters:
v=5, 10, 20 (v/3600 dpi)
h=5, 10, 20 (h/3600 dpi)
Function:
1) TIFF ver. 4.0 format raster graphics compression mode is set from this command
until the <EXIT> command.
2) This supports the TIFF ver. 4.0 compression method.
3) Each of the parameters has the following meaning:
v: printing density in the vertical direction v/3600 (dpi)
h: printing density in the horizontal direction h/3600 (dpi)
Only the following combinations of printing densities in the vertical direction and
in the horizontal direction are permitted:
Vertical direction (dpi) Horizontal direction (dpi)
180 180
180 360
360 360
720 720
4) The commands which are valid in this mode are the following:
<XFER>: transfer graphics image data
<MOVX>: set horizontal position
<MOVY>: set vertical position
<COLR>: set color
<CR>: set printing position in the X direction to the left margin position
<EXIT>: cancel compressed format mode
<MOVXBYTE>:make the unit of horizontal direction setting into byte units
<MOVXDOT>:make the unit of horizontal direction setting into dot units
5) The units for the <MOVX> and <MOVY> commands are the units set by the
ESC (U command.
6) The printing position in the X direction is set to the origin upon the X axis.
Initial State:
Character mode
Related Commands:
Commands related in the direction of applying an effect (Setting)
The full graphics mode set by the ESC (G command is switched to the run-length
encoding compression mode.
Commands related in the direction of receiving an effect (Setting)
The TIFF ver. 4.0 compression mode is canceled by the EXIT command.
