I am bulk printing PDFs on the Dell 5310n laser printer.  The documents are mostly letter size, but occasionally oversized pages are part of PDF files (legal or larger).  I want these all to reduce to letter size when printing.  I have set the Dell print drive to letter size paper throughout.  (In other printers I have used there is a reduce or scale option I don't see in the Dell driver).  I also have page scaling to letter size selected in Acrobat (File>Print>Page Scaling>Reduce to Printer Margins).

When opening one document at a time in Acrobat and printing, the scaling to letter size works (presumably from the Acrobat setting).  But when printing many files at a time, no scaling occurs and legal and oversized pages are clipped.  Thanks in advance for any help here!
