USB printer was working but after cancelling a job, 'usb' does not appear in CUPS


I have a strange problem.

Printing was working without a problem until I had to cancel (rudely by switching the printer off in mid-print). Since then I have been unable to connect, through CUPS, back to the printer.

lsusb detects and shows the printer is connected.
Code:
Bus 001 Device 005: ID 04b8:081e Seiko Epson Corp. MFP Composite Device
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
lpinfo -v does not show any usb option.
Code:
network http
network https
network ipp
network lpd
network smb
I can redirect output to the printer successfully e.g.

Code:
echo $PATH > /dev/usb/lp0
works fine.

In CUPS webadmin searching for the printer does not bring it up like it used to (I guess this is for the same reason that lpinfo -v does not show it).

I have tried various options, to try and force a connection, with the 'Device URI' in CUPS but with no success.

The printer (although I don't think this has anything to do with this problem and has been working previously with no probs whatsoever) is an Epson Colour Stylus R340 and my distro is Gentoo.

I have re-emerged CUPS but with no success. There appears to be no pertinent messages in any of the log files that may relate to this problem. Any ideas?

Thanks

Try using mtink to reset printer.

Also try purging CUPs conf files before reinstalling CUPs

Thanks - tried mtink - hadn't come across that utility before. Although mtink can see and communicate with the printer (tried resetting it) it didn't release what's needed for CUPS to see the printer.

I'm going to dig a bit deeper on unmerging and clearing out CUPS properly before re-emerging.
