Dnes jsem se pustil do souboje se SANE a all-in-one HP Officejet G55. Tisk je u\u017e rozb\u011bhan\u00fd, ale skenov\u00e1n\u00ed je ob\u010das tak\u00e9 t\u0159eba. sane-find-scanner<\/span> tvrdo\u0161\u00edjn\u011b odm\u00edt\u00e1 cokoliv p\u0159iznat, s parametrem -v<\/span> jsem zjistil, \u017ee prohled\u00e1v\u00e1 \/dev\/usb\/scannerX<\/span>, jen\u017ee moje za\u0159\u00edzen\u00ed se nach\u00e1z\u00ed pod \/dev\/2-1.2<\/span>, nev\u00edm pro\u010d, ale nic s t\u00edm nenad\u011bl\u00e1m, snad jedin\u011b symlink do on\u011bch prohled\u00e1van\u00fdch m\u00edst.

Za t\u00edmto \u00fa\u010delem mus\u00ed b\u00fdt jak na stran\u011b klienta, tak serveru odkomentovan\u00fd \u0159\u00e1dek net<\/span> v souboru dll.conf<\/span> a nav\u00edc na stran\u011b klienta p\u0159idat do backendu net<\/span> (net.conf<\/span>) p\u0159idat adresu serveru, bu\u010fto v podob\u011b hostname, \u010di b\u011b\u017en\u00e9 IP adresy. No a v Ubuntu spust\u00edme jednoduch\u00e9 skenov\u00e1n\u00ed a jedeme. Na Windows jsem na\u0161el poveden\u00fd program\u00a0SaneTwain\u00a0<\/b>(http:\/\/sanetwain.ozuzo.net\/<\/a>).<\/p>\n

I own HP OfficeJet G55 which is all-in-one device. My problem is that it’s not situated neither in \/dev\/lp0<\/span> nor \/dev\/usb<\/span> or whatever, but in \/dev\/2-1.2<\/span>. Since sane-find-scanner<\/span> seek the scanner in \/dev\/usb\/scannerX<\/span>, I did:<\/p>\n

mkdir \/dev\/usb<\/span><\/p>\n

and<\/p>\n

\u00a0ln -s \/dev\/2-1.2 \/dev\/usb\/scanner<\/span><\/p>\n

and also<\/p>\n

chmod 666 \/dev\/usb\/scanner<\/span><\/p>\n

Since then\u00a0sane-find-scanner<\/span> find something unrecognzed.<\/p>\n

To \/etc\/sane.d\/dll.conf<\/span> put new row:<\/p>\n

hpaio<\/span><\/p>\n

if you use hplip<\/span>.<\/p>\n

After that scanimage -L<\/span> and also scanimage -T<\/span> should work. Then make scanner useable through network you need xinetd<\/span> configured:<\/p>\n

To \/etc\/xinetd.d\/saned<\/span> put:<\/p>\n

service saned\r\n  {\r\n\u00a0 \u00a0 \u00a0 \u00a0 disable \u00a0 \u00a0 \u00a0 \u00a0= no\r\n\u00a0 \u00a0 \u00a0 \u00a0 socket_type \u00a0 \u00a0= stream\r\n\u00a0 \u00a0 \u00a0 \u00a0 wait \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 = no\r\n\u00a0 \u00a0 \u00a0 \u00a0 user \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 = root\r\n\u00a0 \u00a0 \u00a0 \u00a0 group \u00a0 \u00a0 \u00a0 \u00a0 \u00a0= root\r\n\u00a0 \u00a0 \u00a0 \u00a0 server \u00a0 \u00a0 \u00a0 \u00a0 = \/usr\/sbin\/saned\r\n\u00a0 \u00a0 \u00a0 \u00a0 port \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 = 6566\r\n\u00a0 \u00a0 \u00a0 \u00a0 protocol \u00a0 \u00a0 \u00a0 = tcp\r\n\u00a0 }\r\n<\/pre>\n
To \/etc\/services<\/span> put new row:
\nsane 6566\/tcp #sane port<\/span><\/p>\n
To \/etc\/sane.d\/saned.conf<\/span> add new row:
\n192.168.1.0\/24<\/span><\/p>\n
or another according to your network setup that allowes computers from local network to connect.<\/p>\n
In \/etc\/sane.d\/dll.conf\u00a0<\/span>let the row with net<\/span> uncomented both on server and client side. On client side add to net\u00a0<\/span>backend \/etc\/sane.d\/net.conf<\/span> hostname or IP address of server. That should be all. Now find some sane frontend, in Ubuntu default Easy Scan works well, on Windows I use very good SaneTwain (http:\/\/sanetwain.ozuzo.net\/<\/a>).<\/p>\n","protected":false},"excerpt":{"rendered":"
