DLC Printing Limited to One Network Adapter in Windows NT (113125)


The information in this article applies to:

  • Microsoft Windows NT Workstation 3.5
  • Microsoft Windows NT Server 3.5
  • Microsoft Windows NT Server 3.1
  • Microsoft Windows NT Workstation 3.1
  • Microsoft Windows NT Advanced Server 3.1

SYMPTOMS

With the DLC protocol under Windows NT, you can select only one Network Interface Card (NIC) for printing to Hewlett-Packard Co. (HP) Jetdirect or other network printers. If your Windows NT machine has two NIC's on different network segments with HP Jetdirect printers, you can print to or share a printer from only one segment at a time.

CAUSE

This is a limitation of HPMON, which controls DLC printing in Windows NT.

WORKAROUND

To print to the second NIC (or segment), you have to select a different adapter from the Advanced Options for HP Network Ports option in Print Manager, then reboot the machine.

When you select the Secondary(1) adapter, you are prompted to restart the Spooler service. To do this, run Control Panel, choose Services, select Spooler, choose stop, and then choose start. When you go back into Print Manager and create the printer, the Advanced Options for HP Network Ports dialog box displays the JetDirect addresses on the secondary network adapter.

MORE INFORMATION

By default the HP printer software, HPMON, uses the "primary" adapter setting. If you set up the HP printer on the "secondary" adapter, print jobs will be lost.

The primary or secondary adapters correspond to the first and second NIC's that the DLC protocol is bound to.

To view the DLC binding order:

  1. In Control Panel, choose the Network icon. Choose Bindings. Choose DLC protocol.
  2. From Print Manager, choose the "Printer" connected to the physical HP network print device.
  3. Select settings.
  4. When the "Configure HP Network peripheral port option" window appears, click on the Options button.
  5. The window titled "Advanced option for all HP network ports" appears. The adapter choice is listed here.
  6. Choose the appropriate adapter, according to the DLC protocol binding list, or change the bind order to match the primary and secondary settings.
  7. Open Control Panel - Services, select Spooler, then stop and restart the Spooler service.
  8. Go back to Print Manager and view the HP JetDirect addresses; these addresses are on the network connected to the secondary network adapter.
  9. Select the desired printer and complete printer setup.
NOTE: Since Windows NT does not rely on LANA numbers, changing the binding order does not affect system performance in any way. For more information on binding order, refer to article 103275: How to Find LANA Numbers for Applications.

STATUS

This limitation is by design. HPMON is owned by Hewlett Packard Co.
