Duplex problem

[H. Blischke]

After a number of copies have printed off correctly I start getting the first page printing correctly but with nothing printed on the reverse and an extra sheet printed with the second sheet but shifted some 4cm to the left with 4cm of the print missing.

I see from your error_log that at least the rastertogutenprint filter seems to
work correctly.

My suspicion is that one of the pdf related filters in the filter chain

pstopdf -> pdftoraster

is the culprit.

I'd suggest to do the following:

(1) verify that the pstops filter is installed
(2) verify that the pstoraster filter is installed (or gstoraster, if
    your have Ghostscript 9.01/9.02 installed), or download the gstoraster
    filter from the links.
(3) add a file, say local.convs, to /etc/cups, which defines a filter
    chain that avoids the pstopdf and pdftoraster filters (make sure that
    the cost for this chain is less than the cost of the original chain).
Restart cups after these modifications.

If you need help for this, please post your /etc/cups/*.types and
/etc/cups/*.convs for suggesting the needed changes.
