PRINTER SHARING CARD
Printer sharing between work stations
is a Displaywriter optional feature
for the 40 and 60 CPS printers.
Printer sharing is not supported for
the 15.5 cps printer. One or two sec-
ondary work stations can share the
printer of the primary work station.
In Figure 6-9, the work station that
has the printer sharing card is the
primary work station.
Printing tasks are sent from the sec-
ondary work stations to the primary
work station. The primary work sta-
tion handles printing priority, queu-
ing of printer requests, and
communications with the printer.
The status of the printer is displayed
at the work station that requests
tasks to be printed~
Control of the printer is assigned by
the software, (Textpack I I or above),
and the work station is assigned by
the printer sharing card. Once a work
station has control of the printer, it
maintains control until the operator
releases control or until that work
station I s queue goes empty. Control
will then go to the work station with
the next queue number.
