Setup Printing Estimated reading: 2 minutes Caution: Many special file types, such as .odt or .xls can not be printed by default as they are displayed to the user. If you still want to print them, they must first be converted into pdf files. Limbas will do this automatically if unoconv is installed and is activated CUPS In order to address as many printers as possible via a standardized interface, Limbas uses the Druckersystem, which must also be installed on the server. All printers you want in Limbas must be created there. Note: CUPS provides a user-friendly web frontend with which printers can be created. This is available at http://localhost:631 after being activated with the following command: sudo cupsctl --remote-admin Limbas Configuration Printers created in CUPS can be added in Limbas under Admin -> Setup -> Printers with their own name, which is displayed to the user. The printer marked as Default is preselected by users. By clicking on the gear icon, the settings supported by the printer can be adjusted. If a standard value is already set in the printer, this is indicated in Limbas by a star in front of the value. If no value is selected, but the respective field of a setting is left empty, the printer will take the default value. To order the print, Limbas uses the command lp. All supported options can also be entered in the field selected config. Global Configuration Limbas uses the following commands, to address the CUPS-Server: lpstat for reading out available printers, lpoptions to list supported options and lp, to order documents for printing. With the environment variables lpstat_params, lpoptions_params respectively lp_params additional options for the commands can be defined. Example: The value -E -h 192.168.1.42 causes, for example, that instead of localhost, the CUPS-Server available at the specified IP address is used (-h) and the connection is encrypted (-E).
