Dear Maintainer,

the "Duplex" option of the printer driver seems to be ignored with my OKI B401dn printer, e.g. when printing from Libreoffice or Evince.

Apparently, the option *is* passed to the driver script /usr/lib/cups/filter/rastertookimonochrome.  For testing, I added the line

         exec > /tmp/OKI_OUT 2> /tmp/OKI_ERR

at the very beginning, which dumps the following into /tmp/OKI_ERR:

<snip>
INFO: options = [Duplex=DuplexNoTumble InputSlot=Upper PageSize=A4 job-uuid=urn:uuid:2d08834f-7e7e-37b8-5192-9f4efb9ee1f8 job-originating-host-name=localhost date-time-at-creation= date-time-at-processing= time-at-creation=1567105220 time-at-processing=1567105220 document-name-supplied=eEg7Gt]

INFO: Unkown option = [time-at-processing=1567105220]
INFO: Unkown option = [document-name-supplied=eEg7Gt]
</snip>

On an other (Ubuntu) box, I have a /very/ old Oki PPD (ok400pcl.ppd, Version 1.3, Date 10/15/2008; I don't recall from where I got it) which *does* support Duplex in combination with the (different) rastertookimonochrome script for the aforementioned documents.  However, the printout margins are wrong there, so I would prefer to use the official Debian package.

Any idea how I could fix the issue?

Thanks in advance,
Albrecht.

Hi,

comparing the file OK400PCL.ppd with other ppd's, I noticed an odd extra parameter for Duplex.  Applying the following patch:

</snip>

seems to be /half/ of the solution:

After re-installing the printer, duplex printing works, but /only/ with long-edge binding.  Selecting short-edge binding also prints duplex, but again with long-edge binding, i.e. the “/Tumble true” setting seems to be ignored.  I rarely use that option, but it should work, too…

Thanks,
Albrecht.

Hi Albrecht,

Thank you for the fix. I've forwarded it upstream, but I'm upstream
and I have little clue if this fix is correct. :-(
I created the upstream repository just for publicly archiving the PPD
files which were hard to find and now the can be useful for other
distributions there, as well.

If I get no feedback I plan merging the change in a few months and
updating the package in Debian.

Cheers,
Balint
