GL-AR750s - USB Printer

I have the GL-AR750S router, I’m trying to hook up a USB Printer to the router through the port. I loaded CUP and P910nd, I saw where I can configure the p910nd, and followed the direction through the openwrt wiki, I’m still not getting any connectivity from my Win10 machines to the printer. Does anyone have any ideals?

Long time before I configured printer on the router and I hope that you can refer to this.

Install cups

opkg update
opkg install cups
/etc/init.d/cupsd enable

Add user access

Change /etc/cups/cupsd.conf Pls make sure you use the IP address correct.

User root
Group root
AuthClass Anonymous
Allow from

Check printer info

chmod 700 /usr/lib/cups/backend/usb

And you can see the printer information

DEBUG: list_devices
DEBUG: libusb_get_device_list=2
DEBUG2: Printer found with device ID:

Configure the printer
go to and add your printer. Pls use your root password.

Use printer in windows

The printer address is

Use cache
Cups need to cache printer files. If router’s RAM is not big it may cause problem. So you can ask cups to cache in USB devices.

Modify /etc/cups/cupsd.conf and add your external storage.

RequestRoot /mnt/sda1
TempDir /mnt/sda1

Hi Mr Alzhao, i have a GL-MT300N-V2, i try this configuration, but no access.Please help

You need to check if cups is running normally.

I try for the GL-B1300. I can access to the cups admin interfaces. But I don’t know how to add my printer.
when I type : /usr/share/cups/usb: It’ say :
/usr/share/cups/usb: No such file or directory
DEBUG: list_devices
DEBUG: libusb_get_device_list=5

But no printer found…

Printer is connected (power on) into usb to the mesh node (not the main node which as a usb storage)
I can see 2 defaults printers in the web interface, it’s normal ?
“LP” and “USB” in queue name

Now it’s ok I have add cups on my subnode (with ssh) and my printer work on the subnode usb :slight_smile:

Can you share your experience here?

I simply connected via SSH to the subnode and then installed cups as mentioned above and used the ip address of the subnode to configure the printer in cups.

For those who came here and didn’t get success with CUPS.
For my HP LaserJet Pro M1132 p910nd solution worked perfect without any messing with ppds or drivers for unix.
