Printing via CUPS and attaching files to labfolder logbooks¶
+Follow this guide to set up CUPS virtual printers to be able to print webpages and pictures/files (PDF, PNG, JPG, PS) to one of labfolder’s logbooks, thus, creating a new entry with an attachment. If you are an admin of the labfolder VM read the section Set up CUPS as labfolder admin. Users of labfolder read the section Printing to labfolder projects.
+Set up CUPS as labfolder admin¶
+First, you need to install CUPS on the virtual machine that runs labfolder:
+sudo apt-get install cups cups-client cups-bsd
+Next, configure /etc/cups/cupsd.conf:
# Sample configuration file for the CUPS scheduler. See "man cupsd.conf" for a
+# complete description of this file.
+
+# Log general information in error_log - change "warn" to "debug"
+# for troubleshooting...
+LogLevel debug
+
+# Deactivate CUPS' internal logrotating, as we provide a better one, especially
+# LogLevel debug2 gets usable now
+MaxLogSize 0
+
+# Administrator user group...
+SystemGroup lpadmin
+ServerAdmin <name>@fhi-berlin.mpg.de
+
+HostNameLookups On
+ServerAlias *
+
+# Only listen for connections from the local machine.
+Listen lftest.rz-berlin.mpg.de:631
+Listen /var/run/cups/cups.sock
+
+# Show shared printers on the local network.

+
+# Set the default printer/job policies...
+<Policy default>
+ ... # probably as in the original
+</Policy>
+Change the Server Admin’s e-mail address and the server that shall be listened to (see the Listen statement). Set FileDevice Yes in /etc/cups/cups-files.conf. Now, create a directory where all printers will go, e.g. /usr/local/labfolder/printers.
Get the package for creating new printers from git:
+labfolder@lftest:~$ git clone https://github.molgen.mpg.de/weiher/cupsPrinters
+labfolder@lftest:~$ ls
+cupsPrinters labfolder
+The only file you need to adapt is newPrinter.sh. It is not a must but it is suggested to name the printers like the projects. For example, the FEL projects operating and installation could be placed at .../printers/FEL/operating and .../printers/FEL/installation. Execute the script with sudo rights:
labfolder@lftest:~/cupsPrinters$ sudo ./newPrinter.sh
+To prevent DENIED errors from apparmor install and set the following and restart the CUPS server:
$ sudo apt-get install apparmor-utils apparmor-profiles
+$ sudo aa-complain cupsd
+$ sudo service cups restart
+In case you need to debug some logfiles can be found here: /var/log/syslog, /var/log/cups/error_log and /var/log/cups/acces_log
+One last change is that you need to once add a user named Printer Print (firstname lastname) to the labfolder database. This can be done manually inside the DB by this command:
+$ mysql -u root -p
+Enter password:
+...
+mysql> use labfolder;
+mysql> INSERT INTO user (email, password, firstname, lastname, signupTimestamp, maxStorage) VALUES ('printer@fhi-berlin.mpg.de', '91a13f2aba4a35b00c35dfacadd1d75f4a5171dfa7a465fca9c40e6b007ce982', 'Printer', 'Print', '2018-03-21 10:54:00', '10000000');
+Printing to labfolder projects¶
+The last thing you need to do is to set up a printer operating on your local machine. In Ubuntu Gnome hit Alt+F2 keys and enter system-config-printer. In this printer config interface add a new printer operating as follows:
