Design templates in your word processing, database and financial software that allows for the position of the preprinted logo and let your office printer generate the rest of the document. I no longer preprint my office paper. I just buy blank paper in different colours and textures to use for letterheads and invoices. If I need to change some boiler plate on an invoice or update an email address, I can do it in a minute. Reuse your envelopes.
Envelopes are the black tie of business correspondence.
All of your most serious documents demand one, but careful use of labels can ensure that your envelopes and those you receive can have a second life. Top level correspondence should always go out in a fresh envelope, and you can run small ones through your printer. Give them a bit of class by using a bold version of the document's typeface for the address or a bold version of your company's official font. At fourteen point or so, the average address takes up less than one and a half inches in width and a half an inch of depth. A used envelope addressed like that can be easily reused when a fresh label is stuck over the original address.
