printing just envelopes

I have been using WordStar since about 1981. I have a file with about 8 envelopes, pone per page. When I want to print an envelope, I select the page and print as many as I need. LO seems to only allow me to print 1 envelope per document. In my office, it is inefficient to have to print envelopes that way. I only want to print the return address, unless it a a billing return envelope, etc. How do I do this. There seems to be a lot of interest in printing envelopes, as most questions have a large number of views.
