This command selects the density of the graphics mode.
p DPI (Horizontal) Image dpi vertical #bytes/dot-column
AGM=N AGM=Y
0 72 60 real 72 1 (6-bit mode)
1 144 120 real 72 1 (6-bit mode)
3 216 180 real 72 1 (6-bit mode)
10 180 180 real 180 4 (24-bit mode)
11 360 360 virtual 180 4 (24-bit mode)
If ASF has not been selected (n=15/16/17 or via operator panel), then n=1—4 is ignored. The appropriate
path option must be selected from the System Menu in order for the sheet feeder to work.
ESC P data
Enter dot graphics mode (Device Control String).
ASCII Code ESC P data
Hexadecimal Value X'1B' X'50' data
Decimal Value 27 80
This command enables the dot graphics mode. The density is selected according to the GRM command.
The line spacing value automatically changes if 72-dpi resolution (6-bit mode) is active.
The line spacing value for 180-dpi resolution (24-bit mode) must be selected prior to entering graphics
mode.
In 6-bit mode, only 6 bits of a data byte are required to determine which wires are fired. Therefore, only
one byte is required for each graphics dot column.
In 24-bit mode, 24 bits of four data bytes are required to determine which wires are fired. Only 6 bits of
each byte are used. Therefore, four bytes are required for each graphics dot column.
