|
0x04 ribbon problem
|
|
0x08 ribbon depleted
|
|
|
|
[ss] is either 0x00 or 0x70. Unsure as to its significance; perhaps it
|
|
means paper or ribbon is already set to go?
|
|
|
|
[pg] is as follows:
|
|
|
|
'P' paper 0x11
|
|
'L' paper 0x22
|
|
'C' paper 0x33
|
|
'W' paper 0x44
|
|
|
|
First four bits are paper, second four bits are the ribbon. They aren't
|
|
necessarily identical. So it's possible to have a code of, say,
|
|
0x41 if the 'Wide' paper tray is loaded with a 'P' ribbon. A '0' is used
|
|
to signify nothing being loaded.
