7–114 Digital Emulation
The numeric parameter specifies the number of times to print the character
that follows the repeat introducer. The numeric parameter is a string of
characters in the 30H – 39H range, which is evaluated as a decimal number.
If a numeric parameter is not received or if the parameter is 0, a value of 1 is
assumed. If the parameter is a value larger than the maximum value of
65535, the printer defaults to 65535. All decimal digits are processed as part
of the count.
A repeat sequence is equivalent to receiving the printable character as many
times as specified by the numeric parameter count. A printable character
ends the repeat sequence processing and causes the printer to print.
Set Raster Attributes
Setting the raster attributes determines the size, shape, and position of the
pixels to be drawn.
After entering Sixel Graphics mode, a valid Set Raster Attributes sequence
must be received before the first sixel printable character is received. The Set
Raster Attributes sequence effects all sixel data that follows.
If a Set Raster Attributes sequence is received after a sixel printable character
is received, the printer still recognizes the sequence but disregards all
parameters and continues processing all sixel data and control codes that
follow the sequence, as if the sequence was never received.
If a Set Raster Attributes sequence is received after a sixel control code (21H
– 24H, 2DH), the printer processes the control code and recognizes but
ignores all Set Raster Attributes sequences that follow. If a Set Raster
Attributes sequence is received after an unspecified Digital control code
(20H, 25H – 2CH, 2EH, 2FH, 30H – 3EH), the printer ignores the code and
processes the Set Raster Attribute sequence that follows. Because of this, you
can specify a future control code to be received first, and it will be ignored
without consequence to the Set Raster Attributes sequence until the code is
recognized by the printer.
If a Set Raster Attributes sequence is received before any other sixel control
code, the sequence is processed. The protocol selector has the following
format:
ASCII Code ” Pn1 ; Pn2 ; Pn3 ; Pn4
This selector is defined as follows:
• The double quote (”) sets the raster attributes control characters.
