I've recently started on trying to create letters to send using LaTeX, and I would also like to generate envelopes for those letters at the same time. I discovered the
envlab package which looks like it does an excellent job at that.
The only issue that I'm having is that this puts the envelope content at the end of the document. For my use it would work out better if the envelope were created as the first page of the resulting document. That would allow me to put an envelope into the manual slot of my printer to have that printed and then the printer would pull the paper from the automatic feeder. With the envelope last, my printer just prints the envelope content onto a plain sheet of paper pulled from the tray.
Is there some option that I'm missing which would allow me to reorder the output so that the envelope content would come first?
I'm using pdfTeX 3.1415926-2.4-1.40.13 (TeX Live 2012/Debian).
