this update breaks support for Samsung printers for me. Any attempt to
print via Splix results in an error message, i.e.

  Unsupported format "application/vnd.cups-banner".

or

  lp: Unsupported document-format "application/pdf".

Also, my printers.conf used to contain two lines 

  Filter application/vnd.cups-raw 0 -
  Filter application/vnd.cups-raster 0 rastertoqpdl

..., but those are gone in the new version. I tried adding them again,
but this doesn't seem to make a difference.

Does anyone have a clue how to remedy this problem?

Take care,
Peter
