Notes:
1. The Discard Buffered Data subcommand in the Execute Order Any State command causes the printer to enter
the home state.
2. The End command is valid in any page block, overlay block, or page segment block state and causes the printer
to return to the corresponding page, overlay, or page segment state.
Figure 11 on page 91 shows all of the IPDS states and their commands. Notice that some commands can
only occur in a specific state, some commands can occur in more than one state, and some commands
can occur in any state. Also note that the printer can only enter the page state, the page segment state,
and the overlay state from the home state.
