I found a clever way to make rubber stamps to say whatever happens to be needed at the time. I use my graphics program to create the "stamp" by putting the necessary text in red inside a red outline and print it and cut it out. Then print the letter of transmittal or whatever needs the stamp and re-insert the paper into the feed tray so it will be printed on the face again. Then I put my cut-out stamp on the glass in the proper position for the stamped paper and hit "copy". The printed sheet pulls through and the red rubber stamp prints on the sheet with all the text showing through as if really rubber stamped. You can be creative with your text without spending money for new stamps.
