Sorry, I read the bug report on github more carefully now and realized
that the citation of Till Kamppeter in the last comment of vitorbaptista
is highly relevant in this context:

In my case the PPD has two "Product"-lines:
*Product: "(HP LaserJet 1200)"
*Product: "(Hewlett-Packard HP LaserJet 1200)"

Since the two lines don't represent two different printer models I'd say
one of those two lines could be deleted – and this would fix this bug.
Or is it possible that both lines are needed in some way?

Thanks,
Stefan.
