 Posted: Fri Dec 31, 2004 10:06 am Post subject: Using your flatbed scanner from any pc on the network |
 |
|
Hi everybody!
I own an Epson GT-7000 SCSI Scanner. I am quite satisfied with its speed and picture quality.
On the other hand, my girlfriend only has an old, almost borked usb-scanner connected to
her windows-pc. So i thought about a solution, how she could use my scanner over our LAN.
Since i found no software to do that (ok, i didn't try too hard  ), this is what i did:
Use apache2 and a cgi-bin to scan from network:
Since my scanner device "/dev/sg2" is owned by my everyday user and group root with
permissions 660, i had to change that, to allow user apache access to my scanner:
| Code: | | chmod a+rw /dev/sg2 |
then i wrote this little cgi-bin:
| Code: | | nano -w /var/www/localhost/cgi-bin/scan |
| Code: |
#!/bin/sh
echo Content-type: image/jpeg
echo
scanimage --format tiff --mode Color --resolution 200 | convert tiff:- jpeg:-
|
make it executable:
| Code: | | chmod a+rx /var/www/localhost/cgi-bin/scan |
scanimage is part of sane-backends, convert is part of imagemagick. You will also need
apache, so emerge them, if you don't have already:
| Code: | | USE=tiff emerge sane-backends imagemagick apache |
start apache:
| Code: | | /etc/init.d/apache2 start |
Finally point your browser to the cgi-bin (192.168.0.1 is my pc's ip on our lan):
| Code: | | http://192.168.0.1/cgi-bin/scan |
and there the picture is!
You can change mode and resolution in the script, man scanimage is your friend 
I'm using udev and still have to find out how to permanently change permissions on my
scanner, so i don't have to chmod it after every reboot. Help appreciated 
Hope this is useful to somebody else, too!

| While a web page for scanning is a nice touch, I'm not sure what this buys you over just using sane on the network. If you setup sane to allow network scanning, you can scan directly into gimp from a scanner on a remote machine. |

But does that work from Gimp on a Windows machine? (Like the one he said his GF uses?)
I may be wrong, but I'm thinking probably not.
GREAT Hack there Schurke-- I don't have a whole lot of use for it, but I may try it out just for neat-factor... |

|
|
open up | Code: | | /etc/udev/permissions.d/50-udev.permissions |
with your favorite editor and see if your device is listed in the scanner devices or camera devices section.
If not add it relative to /dev
The syntax of the file should be easy enough to understand.
p.s. Isn't it great how linux allows us to do things like share a scanner over a network and write our own code to do something that isn't natively supported |
