Hi, thanks for your answer

One other advantage of including it in gutemprint is that it would make 
it easy to install the printer without downloading the driver manually. 
Are there guidelines for inclusion?

See attatched the PPD.

I doubled checked to be sure that's the PPD I was using and I created a 
document with LibreOffice and there, the nup setting and the number of 
pages setting worked correctly (perhaps it's handled at the Libreoffice 
level).

I checked with evince, and there:

- selecting 2 pages per sheet gives you 4
- 4 pages per sheet gives you 16
- 6 pages per sheet gives you something like 36

and about the number of copies:

- 2 copies gives you 4
- 3 copies gives you 9

And looking at the PPD, each setting is commented in its own section, 
but there is nothing I see about the nup setting or the number of copies.

Indeed, it seems like the setting is applied twice, perhaps there is a 
missing option in the PPD but I admit I don't know PPD language enough 
to be able to see that.

Thanks.
