SECTION 4
SOFTWARE SPECIFICATIONS Version V 8.0.x
4.1 GENERAL
Before sending any data to the printer, the host should
request status via the serial port to verify any possible fault
conditions.
4.2 COMMAND DESCRIPTION
In the following sections x is defined as ‘0’ or ‘1’, this is
a numeric value where ‘0’ is hex 30 and ‘1’ is hex 31, or whatever
the numeric ‘x’ should be.
4.2 COMMAND DESCRIPTION
Buffer Commands
4.2.1 SET ABSOLUTE HORIZONTAL POSITION (1B 68 x x x x)
When this command is received followed by four ASCII bytes of
position, the next block of text, barcode or graphics data will be
placed starting at the new Horizontal position. The minimum value
is 0000. This will reposition the line pointer to the line start.
The maximum value is determined by width of the print head in dots.
A horizontal position of zero is always the left hand side of the
page
4.2.2 SET ABSOLUTE VERTICAL POSITION (1B 76 x x x x)
When this command is received followed by four ASCII bytes of
position, the next block of text or barcode data will be placed
starting at this coordinate. If the new value is larger then the
current line or page size, the line or page size will be increased.
The minimum value is 0000 this will reposition the line pointer to
the page or line top. The maximum value is determined by the
following formula. Any value larger then the maximum will be
ignored. A vertical position of zero is always the top of the page.
If the YCORD is increased to cause a buffer overflow the YOCRD will
be reset to 0.
Maximum Line Size = 32768/(NUMBER OF PRINTABLE DOTS / 8)
Maximum Page Size = 65536/(NUMBER OF PRINTABLE DOTS / 8)
4.2.3 SET RELATIVE HORIZONTAL COORDINATE (1B 5B x x x x)
When this command is received followed by four bytes of position,
it will be added to the current horizontal coordinate (values are
0000 through the print head width in dots). Any number that sum is
greater than the maximum number of dots per line will be ignored
If the position is preceded by a minus sign the value will move
backwards in the buffer.
