SUMMARY
=======
Most print devices now support bi-directional communications in a local area
network (LAN) to provide feedback to print servers. This information is used in
various dialog boxes (for example, for printer status and current job
information). In Windows NT, bi-directional communication between a print device
and a print server over the network can be accomplished if the following
conditions are met:
- The print device can signal back to the print server (it is a PJL-compatible
print device).
- You are using a communication channel or network protocol that can carry the
signal.
- The print server is using the Windows NT Hewlett-Packard (HP) Network Print
Monitor (HPMON) that expects the signal.
MORE INFORMATION
================
PJL-Compatible Print Device
---------------------------
When communicating with HP's Printer Job Language (PJL) compatible print device
(such as an HP LaserJet IIISi or HP4-series print device) the printer driver
embeds a PJL command in the data stream that causes the print device to send a
signal back to the print server. The signal notifies the server when the page
has finished printing. If the print device understands PJL, bi-directional
printing communication over the network is possible (HPMON must be used in
Windows NT). If your print device does not recognize PJL, you must create a
print monitor for Windows NT that can accept a signal sent from the print
device.
Network Protocol
----------------
Most network protocols support bi-directional printing. Networks protocols such
as the AppleTalk protocol and Data Link Control (DLC) protocol can provide
bi-directional communication in Windows NT. Although TCP/IP can carry the
signal, the Line Printer Remote (LPR) specification has no facility for this
signal. Therefore, the Windows NT TCP/IP protocol does not support network
bi-directional printing.
HPMON
-----
One of the Windows NT Print Monitors, HPMON, supports bi-directional printing
over the network. HPMON uses one of its features called "Advanced Job Status"
for detecting a response signal sent from the print device. This feature is
disabled by default. To enable this feature:
1. From the Print Manager Printer menu, choose Properties.
2. Choose Settings.
3. Choose Port.
4. Select the Advanced Job Status check box.
5. Quit Print Manager.
NOTE: When the HPMON is active, print jobs are not removed from the print queue
unless the print device understands PJL. If the print device does not respond
with a signal to the print server, HPMON informs Print Manager that the print
job is not complete.
