I just installed an Epson nx415 printer on Opensuse 11.1 and I am having trouble configuring for the USB printer port although I managed to configure the scanner by specifying the vendorId and the productId:
usb 0x4b8 0x851
in the /etc/sane.d/epkowa.conf file

I obtained the info from:
sane-find-scanner | grep 0x04b8
found USB scanner (vendor=0x04b8, product=0x0851) at libusb:001:011

The usb device created by udev is /dev/usb/lp0

The CUPS <administrator><find new printer> feature found a printer at the device
URI:usb://EPSON/Stylus%20NX410

and It doesn't work either on the 'print test page'

lp xyz registers a job but it never gets beyong that.

A file gets printed ok if I

cp filename /dev/usb/lp0



I am running out of ideas and need some help please.

Download this
http://www.linuxfromscratch.org/hint.../files/pfs.txt

which explains how to invoke ghostscript to print directly. If this works, as I suspect it will, it will prove your problem is your cups driver. You might just use the script and forget cups altogether.

I guess this would do the work however I use CUPS on my linux box as a server for internet printing from remote window pcs on my local wireless network.

Thanks

Sure, use cups if you want to. The way forwarsd is to get printing with that, and then yo know that your printer with this ppd will make things happen. THEN faultfind cups.

No joy with your pfs.txt.
However it seems that I cannot find the usb port to print to.
The scanner portion of the Epson nx415 works fine, so does the camera card interface BUT NOT the printer portion on the same usb connection.

When I connect the USB cable, the device /dev/usb/lp0 gets created OK but so far seems useless when I
cp t.txt /dev/usp/lp0

Thanks

I wrote the original of that pfs.txt. Where does it break down?
3 steps
1.There's an echo command to wake up the epson printer. Then,
2. cat sometextfile > /dev/usb/lp0 should print or there's a driver or port issue.
