Information about network bi-directional printing support in Windows.

Hello friends,
I have recently bought a HP's Printer. I am not having much idea about a printer. I want to know about the bi-directional printing that are supported by the Windows operating system. Since, you guys explain in simple language, I thought to take some help from you. Please provide some useful information about the network bi-directional printing support in Windows. Hoping that someone would provide the solution fast.!!

Most printing devices now support bi-directional communication in a local area network (LAN) to provide feedback to print servers. This information is used in various dialog boxes (for example, the printer status and information work in progress). The method of bidirectional communication best known as one learns from the first weeks of the informatics program is undoubtedly Telnet or SSH. Although Telnet is easier to use Windows since a customer is built, this protocol is not recommended for security reasons.

In Windows, bidirectional communication between a print device and print server on the network can be achieved if the following conditions are met :

1. The printing device may send a signal to the print server (it is a printing device compatible PJL).
2. You use a network protocol or communication channel with the signal.
3. The print server uses the network of Windows Hewlett-Packard (HP) Printer Monitor (HPMON) awaiting the signal.

When communicating with device compatible printing PJL Printer Job Language Printer (printer device like an HP LaserJet IIISi or a series of HP4) printer driver incorporates a PJL command in the data stream that causes the device of print send a signal to the print server. The signal notifies the server when the page end printing. If the print device understands PJL, print bidirectional communication network is possible (HPMON must be used in Windows). If your print device does not recognize PJL, you must create a print monitor for Windows can accept a signal sent from the printing device.

Most network protocols support bidirectional printing. Network protocols such as AppleTalk protocol and protocol DLC (Data Link Control) can provide bi-directional communication in Windows. To use this technique, and the next, your computer must have a telephone modem or any other means of Internet connection. If you do not have a subscription to an Internet provider, it is always possible to achieve with minimal effort, a PPP connection that will give access to the Internet. Although TCP / IP can carry the signal, the specification LPR (Line Printer Remote) has no function of this signal. Therefore, TCP / IP Windows does not support bidirectional printing network.

Among the print monitors Windows, HPMON, supports bidirectional printing on the network. HPMON uses one of its features called "advanced state of work" to detect a response signal sent from the printing device. This feature is disabled by default. To enable this feature :

1. In the Print Manager Printer menu, choose Properties.
2. Select Settings.
3. Choose the port.
4. Click to check status of work developed.
5. Exit the Print Manager.
