Thanks David for your nice job. my CR-48 can print docs/pdfs with crouton+cups. Now I wonder whether we can scan docs with crouton+sane using local usb scanners.

It should work fine. Have you tried it?

roubao commented 9 years ago

since there is only 16G harddisk, I installed crouton 'core' only, no X. the scanner I'm using is Epson Perfection 2480. Epson provides a package to config/compile/install. But it requires X. so no luck. I am not sure how to skip that requirement.

X11 (without a desktop environment) isn't that big; try just the x11 target. If that's a prereq for what you're trying to do there's not a lot I can help you with there.

It's working now. found George Smart's blog + sane website.

1) sudo apt-get install xsane sane libsane-extras sane-utils netpbm libusb 2) download the firmware:'Esfw41.bin' 3) sudo cp -v Esfw41.bin /lib/firmware/esfw41.bin 4) add 'firmware /lib/firmware/esfw41.bin' to '/etc/sane.d/snapscan.conf' 5) find the scanner: lsusb sane-find-scanner 6) find the device: scanimage -L In my case, it's 'snapscan:libusb:001:005' 7) test it: scanimage -d snapscan:libusb:001:005 --format pnm > out.pnm 8) convert it to jpg: pnmtojpeg out.pnm > out.jpg or sudo scanimage -d snapscan:libusb:001:005 --mode color -x 215 -y 285 --resolution 600 |pnmtojpeg >out.jpg 9) done. Epson package(iscan) looks not a must, neither does X. maybe xsane either.

Thanks for your Crouton making a cheap chromebook a full-functional linux box.

Sweet! Maybe add that to the wiki?
