Cannot print with USB printer connected to FRITZ!Box
A USB printer connected to the FRITZ!Box does not respond to print jobs from a computer in the FRITZ!Box 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 11
- Click
(Start) and then
(Settings) in the Windows task bar.
- Click "Bluetooth & devices" in the "Settings" menu.
- Click "Printers & scanners".
- Click the printer that is connected to the FRITZ!Box.
- Click "Open print queue".
- Click "Printer" in the next window.
- If there is a checkmark in front of the option "Use Printer Offline", click the entry to remove it.
Windows 10
- Click
(Start) and then
(Settings) in the Windows task bar.
- Click "Devices" in the "Settings" menu.
- Click "Printers & scanners".
- Click the printer that is connected to the FRITZ!Box.
- Click "Open queue".
- Click "Printer" in the next window.
- If there is a checkmark in front of the option "Use Printer Offline", click the entry to remove it.
2 Configuring the firewall
- Configure the firewall on the computer so that it allows outgoing connections to TCP port 9100 on the FRITZ!Box. Refer to the manufacturer for information on how to set up the firewall.
3 Printer does not support the operating mode
A printer must be able to process data in RAW format (unidirectional RAW over TCP) to be used as a network printer via USB cable. Printers that require encapsulated or bidirectional data transfer cannot be used as network printers via USB cable. This applies to some GDI printers ("Windows printers"), LIDIL printers ("Lightweight Imaging Device Interface Language"), and DOT4 printers (IEEE 1284 standard), for example.
Workaround
- Use a network cable or Wi-Fi to connect the printer to the FRITZ!Box and configure it as a network printer.
