Raw Bitmap Data Follows
Purpose: Indicates raw bitmap data bytes follow.
Syntax: 0x27[data]
Notes: The printer only uses the first 7 bits of the data byte. If you set a bit to 1,
it prints black. The most significant bit prints farthest to the left. Data
order runs from right to left, so the first dot in a column is the least
significant bit of the first data byte.
Repeat Last Line
Purpose: Causes the printer to copy the previously defined column n number of
times.
Syntax: 0x24n
Values for n range from 0 - 8191.
Notes: The printer automatically increments the X origin of each column. This
command is only valid when preceded by a column of encoded, raw data
or an end of line command.
Transition Black
Purpose: Transition data follows. The first transition is black.
Syntax: 0x25[data,data,...data]
where data specifies the number of black or white dots. Values for data can
range from 0 - 8191.
Notes: Each transition data specifies the number of dots to draw (either black or
white). Each data alternates black and white dot counts.
Transition White
Purpose: Transition data follows. The first transition is white.
Syntax: 0x26[data,data,...data]
Where data specifies the number of black or white dots. Values for data
can range from 0 - 8191.
Notes: Each transition data specifies the number of dots to draw (either black or
white). Each data alternates black and white dot counts.
