Jogging can be enabled through the /Jog parameter of the setpagedevice operator (standard PS3 behaviour). Valid values are:
0: do not jog
1: jog at device deactivation (Not supported)
2: jog at the end of a subset
3: jog at the end of a subset
The behaviour of values 2 and 3 is the same.
The following line will cause the printer to jog after each set:
<< /Jog 3>> setpagedevice
