I'm running 12.04 on a Dell Inspiron Mini 1012, and I recently acquired a HP ScanJet 5200C that I am having trouble using. My searching has led me to this SANE backend for HP printers.
Unfortunately, I am relatively Linux-illiterate, and don't know how to install this library (or whatever it is).
Also, for my particular scanner model, there is apparently another step, which baffles me to the same degree
Support for models 5200C/62X0C/63X0C connected to the USB require the kernel scanner driver or libusb. See sane-usb(5)
Any help, especially direct instructions of what exactly I need to type into the terminal to get this crazy thing working, are much, much appreciated.
