Sixel Graphics Processing
When the 200:100 aspect ratio is selected by Ps1, Pn3 must take on one of
the following values:
1/180 in, change to 200:100 A/R and maintain HGS = 1/180 in
1/140 in, maintain 200:100 A/R and HGS = 1/140 in
1/90 in, maintain 200:100 A/R and change to HGS = 1/140 in
1/70 in, maintain 200:100 A/R and change to HGS = 1/70 in
1/35 in, maintain 200:100 A/R and change to HGS = 1/70 in
When the 100:100 aspect ratio is selected by Ps1, Pn3 must take on one of
the following values:
1/180 in, change to 200:100 A/R and maintain HGS = 1/180 in
1/140 in, maintain 200:100 A/R and change to HGS = 1/140 in
1/90 in, maintain 200:100 A/R and change to HGS = 1/140 in
1/70 in, maintain 200:100 A/R and HGS = 1/70 in
1/35 in, maintain 200:100 A/R and change to HGS = 1/35 in
•
Pn is reserved for future use. If parameters are received, they will be
ignored without terminating this sequence.
•
The final character is designated by the lowercase letter, q, where q
identifies the sequence as the sixel protocol selector and places the
printer in Sixel Graphics mode.
Three control characters cause the Protocol Selector sequence to terminate
and enter Text mode. They are SUB, CAN, and ESC. After the sequence is
terminated and Text mode is entered, the process (SUB, CAN, or ESC)
enacts. All other codes, if received within the Protocol Selector sequence, are
honored without terminating the sequence.
All C1 control codes received while you are defining the Protocol Selector
sequence cause the sequence to terminate and the printer to exit from sixel
character processing. C1 control codes applicable to this printer are then
processed.
Picture Data
Picture data is made up of sixel printable characters and sixel control
characters. All picture data is processed while in Sixel Graphics mode. In this
mode, instead of standard ASCII Text mode processing, characters are
processed by the printer as sixel data, and a graphic image prints.
String Terminator
When the Device Control String parameters have been entered, exit Sixel
Graphics mode using the String Terminator (ST) control code. Exit always
returns the printer to normal text processing.
