I would have thought you could design a summary in Monarch that contains the information you need, in the right groupings and order, and then it would be easy to export this as a PDF if that's what's needed.
You might also be able to script something that can print individual pages of a PDF based on a list of ticket numbers generated by Monarch, but that sounds more complicated to me...
I believe that Olly's correct; you'll need to develop a little script to handle a custom printing sequence of a PDF file. I don't know of any other means to perform what you've described.
I'd be tempted to use develop an [URL="http://www.autoitscript.com/autoit3/"]AutoIT[/URL] script to read in the sequence of page numbers (probably from a text file rather than an Excel file), and then put the right number in the page number field of Print dialog of the PDF viewer, like Adobe Reader.
If you're not accustomed to this type of work, you might be in for a bit of a learning curve. But you may find that it does open some other possibilities for you as well.
Have fun with it,
