I suspect that it is a PDF of a scanned document, as there
is a rubber stamp and signature on the document.

(I assume that the German tax authorities no longer insist
that an invoice or receipt over a certain amount must be
certified with rubber stamp and signature, but I imagine
that some people never give up such practices.)

Exporting as draw gives a file of almost 16MB, which appears
to consist of a single object which is rather larger than
the original A4 contains far too much white space...

The PostScript 3 driver is no help, as the printer does not
understand PostScript 3...
