how do you print wedding invitation envelopes without having to individually type in each address?

i would like to do a mass mailing/printing of the envelopes, is there an easier way to do the envelopes than to type each individual envelope? i need to know if there is a way...this is for wedding invitations. By tooheymom...Do a mail merge. You can download your mailing list from a pda, and create a table on word. Save the document, and use it as a file when you do a mail merge.
That probably will be hard to do as the invitation are going to different people (right) If you had a greeting card software you can print multi pages of envelops as you can put the setting on how many prints that you want, but as I said before, If the invitation are going to different people it probably want work...
