===== Useful commands =====
task can be one of **status start stop restart enable** (start at boot) **is-enabled disable is-active reload is-failed ** . There maybe more tasks. Maybe not all tasks work for a given command\\
These commands should work, must work to have a functional printer setup

|**for i in {29595..29999}; do kill -9 $i; done** or use **killall ccpd** not tested by us|If ccpd gets out of hand you can kill all its processes. First check in which range the process ID's are. Avoid killing unwanted processes. Afterwards do **systemctl status ccpd** to check. Then **systemctl restart ccpd** and check again **systemctl status ccpd**. Now there should be no excess of processes|
===== Useful files =====
  * /etc/[[ccpd.conf]] Make sure your file has the same settings
===== Remarks =====
  * The portnumber might be 59787 (not 59687)
  * ppd: Postscript Printer Driver
  * We presume the printer is installed on a system with systemd. Thus Debian 8 and newer. You can check the Debian version with **cat /etc/debian_version**
===== Installing =====
  * Do NOT connect the printer
  * Open a terminal window
  * Check if CUPS is be installed and started. Do **ps -e | grep cups** and **systemctl status cups**. If not install it
  * Check if Ghostscript is installed with **which ghostscript** and if not install it
  * Do **mkdir /tmp/canon**
  * Become root, stay root and do
    * **<nowiki>if ! [[ -d /var/ccpd ]]; then mkdir /var/ccpd; fi</nowiki>**
    * **<nowiki>if ! [[ -p /var/ccpd/fifo0 ]]; then mkdir /var/ccpd/fifo0; fi</nowiki>**
    * **chown -R lp:lp /var/ccpd**
    * aptitude install libatk1.0-0 libcairo2 libgtk2.0-0 libpango1.0-0 libstdc++6 libxml2 libpopt0
  * Check if apparmor is installed with **dpkg --status apparmor**. If it is installed then
    * Do **aptitude install apparmor-notify**
    * Do **aptitude install apparmor-utils**
  * Download the drivers from the Canon website on Canon UK [[https://www.canon.co.uk/support/consumer_products/products/printers/laser/i-sensys_lbp3010.aspx?type=drivers&language=EN&os=Linux%20(64-bit)|CAPT Printer Driver for Linux V2.71]] Verion 2.71 and save them to /home/user/Downloads
  * **cp /home/user/Downloads/linux-capt-drv-v271-uken.tar.gz /tmp/canon**
  * **cd /tmp/canon/**
  * **tar xf linux-capt-drv-v271-uken.tar.gz**
  * **cd linux-capt-drv-v271-uken**
  * **tar xf Doc/guide-capt-2.7xUK.tar.gz**
  * Check if the computer has a 32 or 64 bit Debian version with **uname -a**
  * We will presume it is a 64 bit computer
  * Start a webbrowser and read the installation instructions in: <nowiki>file:///tmp/canon/linux-capt-drv-v271-uken/Doc/guide-capt-2.7xUK/contents/main_02_01.html#main_02_01</nowiki>
  * With aptitude check if **libglade2-0** is installed and if not install it 
  * Do **cd /tmp/canon/linux-capt-drv-v271-uken/64-bit_Driver/Debian**
  * Do **dpkg -i cndrvcups-common_3.21-1_amd64.deb**
  * Do **dpkg -i cndrvcups-capt_2.71-1_amd64.deb**
  * Restart cups:**systemctl restart cups** or **systemctl stop cups; systemctl start cups**
  * Start ccpd: **systemctl start ccpd**
  * Do **find / -name CNCUPSLBP3050CAPTK.ppd** to check if it exists
  * Do **<nowiki>/usr/sbin/lpadmin -p Canon_LBP3050 -m CNCUPSLBP3050CAPTK.ppd -v ccp:localhost:59787 -E</nowiki>**
  * **/usr/sbin/ccpdadmin -p Canon_LBP3050 -o /dev/usb/lp0**
  * Connect the printer to the USB port (one direct on the mohterboard is preferred) and power
  * Turn the power of the printer on
  * Put paper in the printer
  * Wait until Debian has found and installed the printer. Check in CUPS
    * Open a webbrowser
    * Goto **localhost:631**
    * Click on **Administratoin**
    * Click on the **Manage printer** button
    * Now the printer should be in the list
    * Click on the **Canon_LBP3050** link
    * Click on the **Maintenance** button
    * Click on **Print Self Test Page**
==== What after reboot ====
  * Make sure **ccpd** is started after reboot. If not add **systemctl start ccpd** to **/etc/bashc.bashrc**
===== Issues =====
  * The printjob does not arrive in the print queue so **lpstat -o** yields no output
    * Solution: run
      *  **systemctl restart ccpd; systemctl restart cups; systemctl status ccpd; systemctl status cups**
      * ** /usr/sbin/lpadmin -p Canon_LBP3050 -m CNCUPSLBP3050CAPTK.ppd -v ccp:localhost:59687 -E**
  * The printer does not print the **Print Self Test Page** page
    * **ccp recv_packet error, exit"** You can see this message when you print the testpage and then cancel because it does not get printed. Then go to **Printers | Canon_LBP3050** and click on the **Show All Jobs** button and look in the **State** column
      * Possible solution is to disable apparmor for cups (not for us so far): Do **aa-complain /usr/sbin/cupsd** 
  * **lpinfo --product LBP3050 -m** results in **lpinfo: client-error-not-found**
  * **captstatusui -P Canon_LBP3050** yields **<nowiki>*** captstatusui Socket Error ***</nowiki>**
  * **captstatusui -P Canon_LBP3010** yields **<nowiki>*** captstatusui Error: No Specified Printer ***</nowiki>**
  * **ccpdadmin -p Canon_LBP3010 -o /dev/usb/lp0** yields **<nowiki>Canon_LBP3010 can't find in CUPS Spooler Entry!!</nowiki>**
  * WARNING: gnome-keyring:: couldn't connect to: /home/user/.cache/keyring-hash/pkcs11: No such file or directory
  * After doing **<nowiki>mkdir -p /home/user/.cache/keyring-o6zkvJ/pkcs11</nowiki>** We got: WARNING: gnome-keyring:: couldn't connect to: /home/user/.cache/keyring-hash/pkcs11: Connection refused
  * After a system reboot it might be needed to run **systemctl start ccpd; systemctl start cups**. Check if all  went well with **systemctl status ccpd; systemctl status cups**
  * Error: **ccp send_data error, exit**. Maybe you need to install **libpango1.0-0**
  * CUPS error after doing **Print Self Test Page**: **You are not allowed to print**
  * There seems to be something wrong with captfilter from the **cups-filters** package <code bash>
  # ls -l /usr/bin/captfilter

  </code> Compared with the file in the ** cndrvcups-capt_2.71-1_amd64.deb** file: They are the same
  * tbd
 
==== What might be needed ====
  * dpkg --add-architecture i386
  * aptitude install ia32-libs (ia32-libs is not available on Debian 10 Buster)
  * mkdir /var/ccpd
  * mkfifo /var/ccpd/fifo0
  * chown -R lp:lp /var/ccpd
===== Conclusion =====
So far we did not get the printer to work
