I tried to find how this issue was resolved in other projects. Looks like all
(GTK, Qt, Mozilla, LibreOffice) are detecting if current version of CUPS is 1.2
or newer (this is a minimal version for direct PDF printing). In Qt, this is
done in src/gui/painting/qprinter.cpp:650
if (QCUPSSupport::cupsVersion() >= 10200 && QCUPSSupport().currentPPD()) {
        setOutputFormat(QPrinter::PdfFormat);
        d->outputFormat = QPrinter::NativeFormat;
    }
cupsVersion is declared in src/gui/painting/qcups_p.h:75
static int cupsVersion() { return isAvailable() ?
CUPS_VERSION_MAJOR*10000+CUPS_VERSION_MINOR*100+CUPS_VERSION_PATCH : 0; }
So, it simply uses values from cups.h.

Anyway, do you know any programs which can be used to print PDF directly? lpr
is too complex in case custom print settings are used.
