Apply margin message mode (ColorPOS
®
)
ASCII GS 0x99 l m n o
Hexadecimal 1D 99 l m n o
Decimal 29 153 l m n o
Value of l: l is a binary switch:
0 = disables margin message merging
1 = enable left margin message merging
2 = enable right margin message merging
l > 2 ignore command
Value of m: m is the ID (index) of the logo to be used in the merging. If a logo with index m does not exist or is wider
than the print raster width then this command is ignored.
Value of n: n is the number of raster rows to be empty (skipped) before repeating the designated margin message
merge
Value of o: o is a right – left toggle switch:
o = 0 no toggling of the margin message merge
o = 1 enable toggling, starting with a left margin message rst
o = 2 enable toggling, starting with a right margin message rst
o > 2 ignore entire command
This command performs a dynamic merge of a designated logo/message (or logo/message pair, which can be the
same) into each raster line to be printed after the character data has been placed and in conjunction with any other
active merge modes. The parameter l species whether merging should take place from the left side or the right side.
A left side merge followed by a right side merge (or vice-versa) must be issued, with the latter side merge command
setting the toggle switch = 1 or 2 will create the desired left – right printing eect. Each merge side retains its n value
of raster rows to be skipped. If toggling is not selected when both sides are dened, then if the n skip row values are
dierent, or the logo height sizes are dierent, the side logos will not line up as printing progresses. If toggling is
selected then both left and right sides merge margin message must be dened; otherwise toggling is ignored.
Each side logo can be > ½ of the raster print line. In that case the printing process is additive in the overlap region. This
command with the rst parameter l = 0 turns all margin message merging to o.
Shade and store logo (ColorPOS
®
)
ASCII GS 0x9A n m o
Hexadecimal 1D 9A n m o
Decimal 29 154 n m o
Value of n: n is ID (logo index value) of an existing logo in either ash or RAM memory
Value of m: m is the % of shading to be applied to the logo, 0 <= m <=100.
Value of o: o is the new ID (logo index value) to be used to store the shaded result, according to the current setting of
user storage into ash or RAM.
This command applies shading to an existing logo of any size, storing the result in a new logo at index o. The new logo
is thus better suited for use in a merging mode. The % of shading will have only a few perceptible gradations, so large
increments (20 is suggested) should be used to achieve visibly distinct eects.
