CUPS: Common UNIX Printing System (Presentation)

• Applications will produce output in PostScript
• Create a raster file from the PostScript (ps2raster, usually using Ghostscript in the background)
• Create a printer-language file from the raster data (raster2xxx, using the raster driver of the target printer)
• Send the printer-language file to the printer

2. add the locales you want (for example ru):
$ sudo locale-gen ru_RU
$ sudo locale-gen ru_RU.UTF-8

3. run this update comand
$ sudo update-locale 

or

$ sudo dpkg-reconfigure locales
$ sudo dpkg-reconfigure tzdata
