how to convert to seascape/swap-landscape, or print envelopes?

[Sean Don]

Hello,

I'm relatively new to LaTex, and I've been looking for a way to successfully
print out an address on to an envelope. Please note that my printer will only
take an envelope vertically on the right side of the paper tray.

So far, I've tried putting the address on the top of a landscape document
through LyX, but my HP prints text on the wrong side of the tray; that is, it
prints on the side that is opposite to the envelope's side! I think that if I
could just get seascape or swap-landscape output then I could print onto the
correct side of the paper. Ghostview can *preview* the format I need, but it
cannot actually output what I can see on its window.

I've also tried the envlab latex library, and I've tried a small envelope
program for Linux. I read their guides and played around with LaTex code, but no
matter how nice the envelope preview looked (w/ professional bar codes, etc),
and no matter how nicely my printer chugged away, I was unable to actually get
what the printer was printing onto the envelope.

I bet KDE Office has a wizard to do this, but I don't use KDE. Instead, I
generally compose in LyX. I also recently discovered some Postscript tools
called pstools. However, I'm still unclear as to what I can make them do. Would
pstools help me print in seascape?

Thanks in advance,
Sean
