execute ‘dmesg’ and you will have the console output.

Seems you don’t have the correct driver installed.

Here is my experience to make a printer work.

  1. opkg install cpus

  2. modif /etc/cpus/cupsd.conf

User root
Group root
AuthClass Anonymous
…
Allow from 192.168.8.1/24

  1. execute backend program

$ chmod +x /usr/lib/cups/backend/usb

$ /usr/lib/cpus/backend/usb

You will see some info in console. If you are not using UART, use ‘dmesg’ to show these messages.

Add your printers.

  1. Add printer in your Windows

My printer’s address is http://192.168.8.1:631/printers/Canon_iP3600_series, then you can print now.

  1. Cups need more RAM, which the router may not have. You can let cups to cache in your USB storage if you have.

Modify /etc/cups/cupsd.conf

RequestRoot /mnt/sda1

TempDir /mnt/sda1

 

  1. Add cups in startup

/etc/init.d/cupsd enable
