You can't send terminal escape sequences to a printer.  You probably want to "tr
-d \v" and remove all the characters,  or perhaps you can use "expand" to turn
the tab stops into literal spaces.

There is no ACSII character Ctrl-?, perhaps you mean some application is sending
Esc+? (Hex 1b 3f)  In which case the meaning is implementation specific.
