I'd like to return to this issue of changing paper sizes with single documents, since I think I have a different use case. In my decades-long experience in typesetting scholarly material (the most likely source of very wide tables) I've never found the need to change paper size to accommodate such tables. Possibly, this is because editors force authors to rethink and re-cast their tables to be more easily digestible, i.e., so that the reader can see the data relationships in a simple scan. Also, it's pretty easy to rotate a table on a page so that it reads landscape but the other elements on the page that need to remain portrait -- like headers or footers -- remain in their proper place. This, I think, makes rotating an entire page in mid-document unnecessary or possibly even bad design. On the other hand, there are probably good usage cases for non-academic mixing of page sizes, but that raises the question: what's the relationship between changing paper size mid-document and getting the the printer to change trays? As far as I can tell from my experience with PostScript printers, an unexpected paper-size change (e.g., asking for Legal from a tray that holds Letter) causes the printer to pause with a panel message asking for the operator to switch paper sizes for that tray. I think I've had difficulties even when the printer has the proper size in a different tray. So I don't think we can trust all printers to automatically switch trays. In any case, wouldn't it be safer to assume that a paper-size switch should be accompanied with a paper-tray switch? Also, I think it would be useful to switch trays -- e.g., from plain paper to glossy paper -- in mid-document for the output of high-quality images on the same size of paper. That would make something like a "\X'ps: papertray xx'" or "\X'ps: InputSlot=xx'" very useful. -- Steve -- Steve Izma - Home: 35 Locust St., Kitchener, Ontario, Canada N2H 1W6 E-mail: si...@golden.net phone: 519-745-1313 cell (text only; not frequently checked): 519-998-2684 == The most erroneous stories are those we think we know best – and therefore never scrutinize or question. -- Stephen Jay Gould, *Full House: The Spread of Excellence from Plato to Darwin*, 1996
