Ultimate Raspberry Pi: LAN Print, Scan and PDF Server

Článek jsem měl historicky uložený a pochází ze zdroje, který už neexistuje. Jeho přesná název zněl: Ultimate Raspberry Pi : LAN Print , Scan and PDF Server : CUPS + AirPrint + IPP + cups-pdf + sanescan ( SaneTwain ) + phpSANE / PHP-Scanner-Server ( scanner webinterface ) + samba ( remote file access ).

Datum článku byl 2.4.2014. Samozřejmě už některé věci nebudou aktuální a je potřeba se přizpůsobit. Dávám zde alespoň přepis článku.

service cups restart

Visit the web interface: https://192.168.1.111:631/admin

Steps:

• Log in using:
  • Admin username: pi
  • Admin password: raspberry
• Navigate to Administration → Find New Printers
• Add your printer and enable Share This Printer
• Select your make and model or specify a PPD file.
• Restart services:

service cups restart
service avahi-daemon restart

(Not needed on iOS 7 and above)

Enhanced iOS support:

echo "image/urf urf (0,UNIRAST)" > /usr/share/cups/mime/apple.types
mkdir /opt/AirPrint
cd /opt/AirPrint
wget -O airprint-generate.py --no-check-certificate https://raw.github.com/vidaren/airprint-generate/master/airprint-generate.py
chmod +x airprint-generate.py
./airprint-generate.py -d /etc/avahi/services --cups

Enable scanning support and share a scanner on your network

Install:

apt-get install -f sane-utils xinetd

Enable the saned service:

echo -e "\n192.168.1.0/24" >> /etc/sane.d/saned.conf
sed -i "s|RUN=no|RUN=yes|g" /etc/default/saned

Enable the xinetd sane service:

cat > /etc/xinetd.d/saned <<EOF
# eXtremeSHOK.com
service saned {
    socket_type = stream
    server = /usr/sbin/saned
    protocol = tcp
    user = saned
    group = scanner
    wait = no
    disable = no
}
EOF

BUG FIX: Scanner not working: usbfs: interface 1 claimed by usblp while `scanimage` sets config #1:

echo -e "\nblacklist usblp" >> /etc/modprobe.d/blacklist.conf

Reboot:

sync && shutdown -r now

Verify the scanner is supported and listening:

scanimage -L

Example output:

device `xerox_mfp:libusb:001:004' is a Samsung Samsung SCX-4623 Series multi-function peripheral

Verify the service:

cat /etc/services | grep sane

Example output:

sane-port 6566/tcp sane saned # SANE network scanner daemon
