[gentoo-user] telling hpaio / sane what scanners are present

[Allan Gottlieb]

Two problems identifying scanners

ajglap ~ # scanimage -L
device `hpaio:/usb/HP_LaserJet_1200?device=/dev/usb/lp0' is a hp HP_LaserJet_1200 multi-function peripheral
ajglap ~ # 

This is wrong.  I do indeed have HP laserjet 1200 attached via usb,
but it is a printer not a multifunction device.

The second problem is that there is on the network (at location
192.168.1.50) a real multifunction device, HP officejet 7310.

This is not found.

Add'l info

When at another location with no laserjet but with a USB multifunction
device (officejet 7130 -- not 7310), all is well.

If at the original site I try scanimage without -L, it faults (see
below).

thanks in advance for any help,
allan
