USB Printer not working with TomatoUSB

stubbornboy 2,277 366 August 30, 2010 at 05:51 AM
Router is NetGear WNR3500L and version of Tomato I have installed is Teddy_Bear mod mentioned here - http://www.linksysinfo.org/forums...hp?t=63587

I ahve tried a Canon D340 printer as well as Brother MFC665CW and both ill not show up under "attached devices" in the Tomato Screen when I plug them into the USB port.
Is there anyone here successfully using this router with TomatoUSB?

thx

I'm just curious, why would you attach a wireless printer (MFC-665CW) to a wireless print server over USB?? Even if you insist on doing so, realize you’ll lose a lot of functionality. Any printer over TomatoUSB is only going to support basic printing functions. You won’t even get feedback from the ink monitoring app in the system tray (I have this printer as well, so I’m quite familiar with it).

I'm using the teddy bear mod (the predecessor to TomatoUSB) w/ my WL-520GU router and it works fine w/ my Brother HL-2140 (laser), Samsung ML-2020 (laser) and Canon S820 (inkjet). Of course, I'm using a USB hub (powered) since the WL-520GU only has a single USB port. Also, you need to initiate additional p910nd processes to handle more than one printer, which you add to Administration->Scripts:

/usr/sbin/p910nd -b -f /dev/usb/lp1 1
/usr/sbin/p910nd -b -f /dev/usb/lp2 2
/usr/sbin/p910nd -b -f /dev/usb/lp3 3

This will establish p910nd processes on ports 9101, 9102, and 9103, respectively, and need to be specified when you configure the printer drivers (the port 9100 process is already established by TomatoUSB upon installation). IOW, if the problem is trying to see multiple printers, you need to do this.

This will establish p910nd processes on ports 9101, 9102, and 9103, respectively, and need to be specified when you configure the printer drivers. I assume you've done this.
. The p910nd process is running (only one since I didn't requrie two devices) and I can telnet to the print server port on the router also. Actually I am at work, so I can't get the logs. It detects the printer I believe, but IIRC then it errors saying "/usb/something..." not found. I'll post the exact message when I get back home

I just tried MFC-665CW to test if my issue was a printer specific problem (related to Canon D340). The intent is to use the Canon D340.

Make sure you have both USB 1.1 and 2.0 enabled in the USB settings. This may or may not be the issue, but has worked for me for a couple of printers.
