Graphics Printing
TTPM2 can print bit map graphics. Graphic images are stored in the fixed memory area and
will therefore be repeated on every ticket until the next !C command is received.
Remember, when creating graphics for the TTPM2 printer, that the pixels are not square but
have a height/width ratio of 1.32:1.
Syntax for defining and downloading graphics data is as follows:
!F G <orientation> <xpos> <ypos> 1 <height> <width> 1_<Graphic_data>
!F G Format graphics for printing
!F Command to load print-parameter information.
G Indicates graphics mode.
<orientation> Print orientation. This is ignored in graphics mode. Orientation is always
North (N). The printer requires the N to be inserted.
xpos Horizontal starting position in pixels for the upper left-hand corner of the
graphics block. Position will automatically be rounded off to be divisible
by 8 as a graphic block has to start at the first bit in a byte.
ypos Vertical starting position in pixels for the upper left corner of the graphics
block.
1 Not used for graphics printing. Must be set to 1.
height Height in pixel lines of the graphic block. The length of the ticket
determines maximum height. For an 86 mm ticket the maximum height is
approximately 500 pixel-lines.
width Width in bytes of the graphic block. Maximum width is 48 bytes.
1 Not used for graphics printing. Must be set to 1.
space One space has to follow the "1" before the graphics data.
Graphic_data This is a block of bit mapped graphics data. The block is stored in the
printer starting at <xpos>, <ypos>. The numbers of bytes specified by
<width> are stored in one pixel line. The <ypos> is then incremented and
the next line is stored. This is repeated <height> number of times. It is up
to the user to send the correct number of bytes to the printer, that is,
<height> × <width>, as the printer will scan the input character stream for
the correct number of bytes.
