I think I figured it out. I changed reformed to use a "generic IPP printer"
and used a connection string of ipp://ryle/printers/bw_L2300D. This way,
reformed sends the document in PDF format to ryle which is able to run
filters pdftopdf, gstoraster, rastertobrlaser which works fine. Sorry for
the interruption.
