[Issue Unconfirmed]
The "print-scaling" / "print-scaling-default" / "print-scaling-supported"
attributes defined in 5100.16-2013 were moved to IPP Driver Replacement
Extensions v2.0 and although the sections were removed from 5100.16 and the
overview of changes states this move, the table of contents still lists
sections for "print-scaling" / "print-scaling-default" /
"print-scaling-supported".
