The Unit ID Number and the printer port number then become the
default unit and printer assignment numbers for that computer. All
subsequent print jobs sent without a printer select sequence will be
sent to this unit/printer port by default. If you desire to send print jobs
to the same printer, the Printer Select Code, Unit ID Number, and
printer port number do not need to be sent again.
If you wish to select another printer on any unit without changing the
default unit and port assignment numbers, send the Printer Select
Code, capital T, the desired unit ID number, and the desired printer
port number. The next print job sent will be sent to the temporary
unit/printer. Subsequent print jobs without a Printer Select Code will
be sent to the default unit/printer.
If you send an invalid printer select sequence, various conditions will
determine where the print job is sent. In any case, the print job should
be immediately resent with a valid Printer Select Code.
The clear buffer command described in
Section 6.2.6
will only clear
the buffer on the unit to which the computer sending the data is
connected. If all or part of the data has already been passed to the
buffer of another cascaded unit, that buffer will not be cleared.
The utility software may be used with Option 19 units to send the
printer select sequence.
