print a single postcard-not 2 or 4/page

[flower lady]

I am attempting to print on a postcard 4.25x5.5" - I already have the
postcards and they are single - not 2 or 4 on a page and can't figure out how
to do it.

File > Page Setup > Printer and Paper.

Set your paper size there before setting your page size in the Layout tab of
the Page Setup dialog.
