The `lp` and `lpr` commands now provide better error messages when the default printer cannot be found (Issue #5096) - berkeley/lpr.c: Use cupsLastErrorMessage() for not-found errors. - cups/dest.c: Set the last error message in cupsGetNamedDest(). - systemv/lp.c: Use cupsLastErrorMessage() for not-found errors.
Do some code reorganization so that all of the PPD code is separate from the rest. Note: cupsGetPPD* and friends are now in cups/ppd.h now - should not be an issue but was necessary to leave a clean break for future code. git-svn-id: svn+ssh://src.apple.com/svn/cups/cups.org/trunk@13007 a1ca3aef-8c08-0410-bb20-df032aa958be
