Port Switching – Programming Considerations

not already at the top of form. All other states of the printer such as the currently selected form,
character pitch, character attributes, line pitch, etc. are under the control of the programmer(s).
The best programming practice is for the programs at each host to leave the printer in a “clean” state.
This means that all programmers on all the hosts should probably agree on some known state that they
can all expect to find the printer in, and be expected to leave the printer in when their program is
finished.
In addition to the various control and escape sequences described in this manual, additional
consideration is required if an Imager or ImagerPlus Co-Processor is installed. All data from all ports
will pass through the co-processor. Therefore, if one host leaves the Imager or ImagerPlus in a
particular state, it may affect data received from another host.
