7–117Digital Emulation
printed after entering Sixel Graphics mode. GCR allows sixel data to
overprint lines by consecutively starting at the same horizontal position. For
example, if the first sixel data prints at column 10, the GCR causes the next
line of sixel data to start at column 10 and not at the left margin.
Graphic New Line (–)
The Graphic New Line (GNL) control code initiates printing, causes the
active position to move to the furthest left position, and advances paper by
one sixel height.
Numeric Parameters (0 – 9)
Some graphic control codes may be followed by a numeric value that is
encoded as an ASCII decimal number (0 – 9) in the 30H – 39H range. A
numeric value is terminated by any non–digit, specifically another control
code or a graphics printable character. The default for any numeric parameter
is 0.
Parameter Separator (;)
The parameter separator is used to separate a series of numeric parameters. If
a number does not precede the separator or does not follow the separator, the
printer assumes a value of zero.
ASCII Control Characters
In Sixel Graphics mode, the printer ignores all CO control characters
received except CAN, SUB, and ESC. When the printer receives a CAN
control character, it terminates Sixel graphics mode. A SUB control character
is processed as 3FH (one sixel space), which limits the effect of some
