FRITZ!Box 7330 Service

Printer does not print when used as a network printer

A USB printer that is connected to the FRITZ!Box and configured as a network printer does not respond to print jobs from a computer in the home network.

Simply proceed as described below. After each measure, check whether the problem is solved.

1 Disabling the option "use printer online" for the printer

The following step is only necessary if you are sending the print jobs from a Windows computer:

Windows 10

  1. Click (Start) and then (Settings) in the Windows task bar.
  2. Click "Devices" and then "Printers & Scanners" in the "Settings" menu.
  3. In the section "Printers & Scanners", right-click the printer that is connected to the FRITZ!Box.
  4. Click "Open queue".
  5. Call up the "Printer" menu in the next window.
  6. If there is a checkmark in front of the option "Use Printer Offline", click the entry to remove it.

Windows 8

  1. Press the keyboard shortcut Windows key + X and select "Control Panel" from the context menu.
  2. Click "Hardware and Sound" and then "Devices and Printers" in the "Control Panel" menu.
  3. Right-click the printer that is connected to the FRITZ!Box.
  4. Select "See what's printing" from the context menu.
  5. Call up the "Printer" menu in the next window.
  6. If there is a checkmark in front of the option "Use Printer Offline", click the entry to remove it.

Windows 7

  1. In Windows, click "Start" and then "Devices and Printers".
  2. Right-click the printer that is connected to the FRITZ!Box.
  3. Select "See what's printing" from the context menu.
  4. Call up the "Printer" menu in the next window.
  5. If there is a checkmark in front of the option "Use Printer Offline", click the entry to remove it.

2 Disabling bidirectional support for the printer

Windows 10 / 8:

The option "enable bidirectional support" cannot be enabled for network printers in Windows 10 and Windows 8. It is therefore not necessary to adjust the printer settings.

Windows 7:

  1. In Windows, click "Start" and then "Devices and Printers".
  2. Right-click the printer that is connected to the FRITZ!Box and select "Printer properties" from the context menu.
  3. Switch to the "Ports" tab.
  4. Disable the option "Enable bidirectional support".
  5. Click "Apply" to save the settings.

macOS, Linux, and other operating systems:

  1. Disable bidirectional support for the printer. Information on the procedure can be obtained from the manufacturer, or refer to the operating system's help.

3 Configuring the firewall

  1. Configure the computer's firewall so that it allows outgoing connections to TCP port 9100 on the FRITZ!Box. Information on how to set up the firewall can be obtained from the manufacturer.

4 The FRITZ!Box does not support the printer

Printers must be able to receive data in RAW format (unidirectional RAW over TCP) in order to be used as network printers. USB printers that require encapsulated or bidirectional data transfer cannot be used as network printers. This is the case with some GDI printers ("Windows printers"), LIDIL printers ("Lightweight Imaging Device Interface Language") as well as DOT4 printers (IEEE 1284 standard), for example.

Workaround

The FRITZ!Box USB remote connection software enables you to use USB printers with the FRITZ!Box, even if they cannot be used as network printers with the FRITZ!Box:

  1. Use the FRITZ!Box USB remote connection to connect your printer to the computer.
