Installation of cups-bsd did the trick. BTW, I tried installing lpr before and it did not help. This is weird, since I've looked into my i386 installation and neither cups-bsd, nor lprng, nor lpr are installed there. Why all at sudden cups- bsd was necessary on amd64? Oh, well, what is important - it works now. Thank you for helping me out.
