I would like to use a Raspberry Pi as a virtual pdf printer.

I ran sudo apt-get install printer-driver-cups-pdf and logged into 192.168.1.225:631 which is the static IP of my Pi. Afterwards I created a virtual printer with the name pdf_wydruk. (I check in Share printer during the create process). I opened a random picture and clicked print, chose pdf-wydruk to use and nothing.

I cannot find this file anywhere! I created /home/pi/PDF because I read this is the default path. I checked another default folder /var/spool/cups-pds/ANONYMOUS. I found 0.pdf with the actual time of editing but that file is empty - I don't have any picture or text from my desktop.

The version of Raspbian I am using is:

pi@raspberrypi:/var/log/cups $ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
NAME="Raspbian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"

ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"

1 Answer 1

Reset to default

Ok i installed at the fresh image of raspberry pi and that works. Probably i had have something bad set in privillege.

  1. installed only cups for first sudo apt install cups

  2. i check my ip at ethernet/wifi via ifconfig

  3. I open configuration file for cups

    sudo vim /etc/cups/cupsd.conf

i find them line Listen localhost:631 and change them to Port 631

next - i added Allow @local in three places - result below

<Location />
  Order allow,deny
  Allow @local
</Location>

# Restrict access to the admin pages...
<Location /admin>
  Order allow,deny
  Allow @local
</Location>

# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Default
  Require user @SYSTEM
  Order allow,deny
  Allow @local
</Location>

  1. I restarted services - sudo service cups restart now i should access at my desktop to raspberry cups by url 192.168.1.225:631 ( i get that ip from ifconfig command )

  2. i added usermod for pi

    sudo usermod -a -G lpadmin pi

  3. I installed cups-pdf -- now they have new name 'printer-driver-cups-pdf`

    sudo apt-get install printer-driver-cups-pdf

  4. I added printer generic --> generic-cups-pdf like guy at that spanish movie

https://www.youtube.com/watch?v=ZHQuCkrqTS4 administration -> add printer -> cups-pdf -> i called printer-pdf polish pdf-wydruk

8) i created folder at raspberry pi /home/pi/PDF

At ip_raspberry_pi:631 in browser click Printers -> Maintenance --> Print test page --- and ... i should have test pdf file at my raspberry /home/pi/PDF if you don't find - check /var/spool/cups-pdf folder and should be folder pi or ANONYMOUS and looking for that pdf file.

  1. In my project i have wanted share that file for other computer in network so i install samba

sudo apt install samba i said no to window with ask, because i don't need settings WINS with DHCP - I set static ip for raspberry pi

I created folder /samba/wydruki

sudo mkdir -p /samba/wydruki
sudo chmod -R 777 /samba/wydruki
sudo chmod -R nobody.nogroup /samba/wydruki
sudo chmod -R 777 /samba
  1. I changed to settings file using sudo vim /etc/samba/smb.conf
[Publiczny]
    path = /samba/wydruki
    browseable = yes
    guest ok = yes
    read only = no
    create_mask = 777
  1. I restarted services samba
    sudo service smbd restart
    sudo service nmbd restart
  1. I changed file conf cups-pdf
    sudo vim /etc/cups/cups-pdf.conf

and i comment two old line and added new with path to /samba/wydruki

##  CUPS-PDF output directory 
##  special qualifiers: 
##     ${HOME} will be expanded to the user's home directory
##     ${USER} will be expanded to the user name
##  in case it is an NFS export make sure it is exported without
##  root_squash!
##  on Ubuntu, the cupsd AppArmor profile needs to be updated
##  to match the output path as per instructions in LP:147551
### Default: /var/spool/cups-pdf/${USER}

#Out ${HOME}/PDF
Out /samba/wydruki

### Key: AnonDirName (config)
##  ABSOLUTE path for anonymously created PDF files
##  if anonymous access is disabled this setting has no effect
### Default: /var/spool/cups-pdf/ANONYMOUS

#AnonDirName /var/spool/cups-pdf/ANONYMOUS
AnonDirName /samba/wydruki
