TX/CX 4000
7.2 PC/LAN Printing
The TX/CX 4000 offers a serial and
a parallel port to share the printer
with PCs or LANs. Simply connect
the PC/LAN printer server to the
parallel or serial port. You can use
just one or both of these sharing
ports.
All data streams received by the
TX/CX 4000 will be directed to the
output port specified through the
active configuration. The output
port can be changed through the
front panel or through Host/PC
download command 66. Unless the
Host/PC download command is
placed on the first line in the first
possible position of the document,
the output port will not be changed
until the whole document is printed.
Select output port option 0 or 1,
since the initialization feature only
applies to switching printers during
coax host printing.
The output printer specified in the
TX/CX 4000’s configuration
(through the front panel or through
Host/PC download command 60) is
irrelevant for printing from one of
the shared ports. For PC/LAN
printing, select the appropriate
printer driver on the PC/LAN
printer server.
PC printing longer than 10-20
minutes (depends on host
configuration) may cause the 3270-
type host to drop communication
with the printer (“go to sleep”).
7.3 Parallel and/or Serial
Initialization
If you want to change the printer’s
configuration for shared printing
(e.g. set it to PostScript mode), use
the parallel and/or serial
initialization strings (Host/PC
download commands 56 and 58
respectively). Consult the printer’s
user’s guide for the ASCII hex values
representing the desired
configuration commands. Then
store these commands in the
TX/CX 4000’s memory using
Host/PC download commands 56
and/or 58.
After the host printing is
completed, and before the print job
from the parallel or serial shared
port is sent to the printer, the
interface will send this initialization
string to the printer and configure it
according to your instructions.
However, it is possible that the print
job coming through the
parallel/serial shared port contains
other printer instructions, thus
overriding the parallel/serial
initialization string.
