When you want to create a Passthrough printer, you first use the Management Console to create a port that the Passthrough printer will use. When you create this port, you must select a port monitor that supports the attachment type for your printer. For example, if your printer is local or parallel-attached, select the Local Port; if your printer is TCP/IP attached, use a TCP/IP port monitor designed for that printer.
Then you use the InfoPrint Manager Administration GUI to create the Passthrough printer, specifying the port you just created.
To see a list of ports that are available on your system, complete these:
- Click the Windows Start button and select Settings → Printers.
- In the Printers window, select File → Server Properties, and in the Print Server Properties window, click Ports.
InfoPrint Manager automatically creates a Windows printer (named IPM-<actual destination name>) that uses the port you named, along with the Generic / Text Only printer driver. The Generic / Text Only driver is considered a passthrough driver because it does not change the data stream it receives. If you send PostScript to it, it sends the same PostScript to the printer.
