PRINTER SHARING
If the C82315* is connected to a PC with the Parallel Sharing Cable,
the PC must be turned on.
The C62315* Interface is equipped with two interface connectors: a serial connec-
tor for connecting the twinax V-connector and a parallel connector. By connecting
a PC to the parallel connector, you can share the printer between the PC and
Twinax systems.
When you first turn the printer on, the twinax connector is selected. If the twinax
system sends no data for a certain period, and the PC system sends data, the
interface switches to the parallel connector. (The period the interface wafts before
switching can be set with Display station Setup or Command 06 described in
Interface Setup Commands--the default is 8 seconds.)
After a print job is completed from either connector, and no additional data is
received for a certain period, the interface monitors both connectors for the next
data.
Since printing alternates between the twinax and PC systems during printer
sharing, it is recommended that you reset the printer at the beginning of each
print job. Otherwise, page layout, character spacing, and other settings remain
from the previous print job.
You can use Command 09 described in Interface Setup Commands to define a
string of up to 25 characters that are sent to the printer each time the interface
switches to the parallel connector.
The interface automatically restores settings for character pitch, lines per inch, and
page length when lt returns to twinax printing.
