Operation-Coax; Printer Sharing - Black Box PC124C Installation Manual

10. Operation—Coax
When the printer is turned on, the interface checks for a proper 9-pin host
attachment cable to decide which mode of operation is desired. If a twinax or coax
cable is not attached, the Laser Card will cause an error page to be printed. Power
OFF the printer, attach the adapter, and then power ON the printer again.

10.1 Printer Sharing

The Laser Card allows your printer to automatically share printing from an
attached PC (any parallel or serial source), an attached LAN (through an
additional network card), and an IBM coax host. The interface uses a timeout after
each host print job before the interface allows the printer to honor PC/LAN jobs.
Make sure the printer is loaded with paper and "READY" is displayed before
printing.
When the printer receives PC/LAN (ASCII) data and the host attachment is not
active, it honors the ASCII job. At the completion of the ASCII job, the printer has
a timeout setting so it will wait and not accept data from another source.
If it seems that the printer is not printing host data for a extended time
after an ASCII job, check, and possibly change, the printer-sharing
timeout in the printer.
If the PC print job is sent while a host job is printing, the printer responds as
"busy" to the PC/LAN print request. The print job can be spooled through a spool
program, sent to the printer when the host job is finished, or if the PC's printer
port is set for infinite retry through the DOS "Configure Printer" command
(described in the DOS manual), the print job waits for the printer to be available
to receive the data.
If the interface's timeout setting is too short (less than 4 seconds), it is
possible the interface will interpret an interruption of a host print job as
the end of the job and switch to PC/LAN printing.
