hplip-dbg 3.15.7-0ubuntu4 (amd64 binary) in ubuntu wily

 The HP Linux Printing and Imaging System provides full support for
 printing on most HP SFP (single function peripheral) inkjets and many
 LaserJets, and for scanning, sending faxes and for photo-card access on
 most HP MFP (multi-function peripheral) printers.
 .
 This package contains debugging symbolic information for all the
 binaries and libraries in the hplip and hpijs packages.
 .
 It is useful for generating backtraces using debuggers like
 gdb and to get better information from tools like ltrace.
