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)

<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.
