Printing PDFs with more than one page size

A large client sent me a PDF of mostly usLetter-sized pages, but with some
in-line 11 x 17" pages he intended to Z-fold. I was able to vary the size
of the bounding box within the Windows drivers by selecting "Choose Paper
Source by PDF page size". That way I would eliminate the vast white spaces
created by putting letter-sized images within an 11 x 17" bounding box, or
alternatively, shrinking or masking 11 x 17" images to fit a letter-sized
bounding box. With the advanced settings of our printer's drivers, I was able to
program the two paper sizes into the print job.

Norman,

Is there any reason you cannot just use several print jobs? Low tech but 
it should work.

Mike, it's a production run with lots of copies and lots of pages per copy, so
it'd be too labor intensive to be cost effective if there's a high-tech way of
doing it.

That way is to put it on a Windows workstation to gain access to the
"Choose Paper Source by PDF page size" control that the MS drivers
offer. This sets the bounding box rather than the paper as the interface
mistakenly indicates.

Then use the PCL drivers because of the way Microsoft's PS drivers position the
images.

Make sure to set your letter-sized body pages to 2-sided and, if you can, your
Ledger-sized pages to 2-sided, flip on short edge.
