The Pages category allows you to ensure that the document’s page size is printable according to the paper boundaries defined by the document’s Print record. The Pages category is divided into the Page Size and Paper Size controls.
Page Size Controls
Check either the Width or Height box to be alerted when the page dimensions are not within the printable area allowed by the chosen printer type (PPD).
Paper Size Controls
Check the Paper Width box to be alerted when the paper width (a user-defined value specified within the application’s Page Setup) is greater than the Print record’s page width.
If the paper width is less than the document’s width, then obviously the printout will be undesirably “clipped”.
