Typing envelopes is a practical use for a typewriter.
By the time you:
- open a WP program
- find “Envelopes and Labels”
- choose label
- copy addressd
- paste address
- connect printer
- change printer paper feed
- confirm paper change
- reject “black ink low” warning
- insert envelope
- print envelope
- throw away envelope for improper geometry
- print envelope successfully
My envelope was already typed.
BTW, if you don’t use an ink-jet printer, because laser printers use plastic as ink, the plastic will wear off as the envelope passes through automatic sorting systems.
This isn’t an issue with impressions made using a typewriter ribbon.
