Thanks to both for replies. The printer is now being detected according
to dmesg but I can't see where it is attached. (I am not usiing CUPS and
would only do so as a last resort!
The relevant portion of dmesg is:
2925.412931] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 2925.412936] usb 1-2: Product: Samsung ML-2570 Series
[ 2925.412941] usb 1-2: Manufacturer: Samsung
[ 2925.412945] usb 1-2: SerialNumber: 3W37BKAQ610114P
[ 2925.891211] usblp0: USB Bidirectional printer dev 8 if 0 alt 0 proto 2 vid 0x04E8 pid 0x327C
[ 2925.891229] usbcore: registered new interface driver usblp
So it's there soewhere, but where?
