Hello Mr. Alan,
Sorry for delayed reply, I just could not spare time for this hobby of mine...
So, the thing was, that I did not set the printer.

After that, it is printing, but I have major issue...
It prints text files (.txt) and .pdf just fine.
And .png files (pictures) it prints on 4 papers.
I guess I have to set some parameters for this.
But I can not print OO file (.odt) or MS offoce (.doc) files.
If I look at CUPS I can see that those print jobs are under "Completed jobs"
as if they were printed, when they are not...
Code:
grom@C6820s ~ $ lpr Desktop/pogled.png
grom@C6820s ~ $ lpr Desktop/Programerska\ naloga.pdf
grom@C6820s ~ $ lpr Desktop/Programerska\ naloga.doc
grom@C6820s ~ $ lpr Desktop/Programerska\ naloga.odt
looking at CUPS:
