My Samsung SCX-4200 printer recently stopped working all of a sudden (net-print/cups-1.5.2-r4 was reinstalled 2 days ago). Even after a restart, printing doesn't work (e.g. when printing a test page from the web administration interface). It appears that the /usr/libexec/cups/filter/rastertoqpdl process hangs. I have net-print/cups-1.5.2-r4 and net-print/splix-2.0.0_p20111206.

Thanks for the detailed report! I have a SCX-4200W and it still works fine, but I use ~arch cups I'll try and downgrade my setup at home to stable to check this
After a downgrade to 1.5.2-r4, re-merge of splix and update of the ppd file, it still works for me here Can you try to update the ppd file again to be on the safe side? (ie remove it from /etc/cups/ppd and go through "Modify printer" to set it again). Else this may be a hardened problem, but I am not sure where to look at this
Don't hesitate to reopen if updating the ppd file did not work
