Next, the installation and configuration processes of the two plug-ins are introduced respectively.

Connect the printer to the USB interface of the router and input the instructions.

You should be able to see the lp0 device.

Locate the service print server and check the startup.

Fill the device with /dev/usb/lp0 you just saw, and choose lan as the interface. The port is usually 9 100.

First, install the driver corresponding to the printer. In this case, the printer I use is Canon MG2580s.

Settings-Devices-Printers and Scanners-Add Printer-The printer I need is not in the list.

Select to add a printer using a TCP/IP address or host name, and then click Next.

Select TCP/IP device as the device type, fill in the host name or IP address in the router gateway, uncheck the automatic query driver, and then click Next.

Wait for the automatic detection to fail, select Customize, click Settings, check whether the port is the same as the previously set 9 100, and click Next after confirmation.

Find the driver corresponding to the printer, Canon-Canon MG2500 series printer.

You're done. Enjoy it!

note:

: Sometimes when printing, I can't find the device. Usually, the communication between the printer and the router is not smooth. Just go to the router management to find the p9 10nd service and restart it.

Install the common plug-in first:

After that, we need to install sane-backends, which is similar to the scanner driver interface. If it's too big to install this package directly, we just need to choose driver package which is suitable for our printer model.

You can check whether the installation is successful through the scanimage -L command. If the printer is connected properly and the corresponding backend is installed, you should be able to see the following effects:

Edit/etc /etc/sane.d/saned.conf

Check whether /etc/services has a normal port. Usually, sane-daemon is added automatically during installation. If not, it will be added manually after the file.

Edit /etc/xinetd.d/sane add

Finally, in the system startup item of LUCI interface, find xinetd and set it to enabled.

Under windows, you need to use sanetwain client to scan. After opening the client, set the host name to the router gateway and the port number to 6566, and start scanning.
