When a printer is to be used in an interactive mode (as a typewriter), a fundamental problem that is faced is that certain keystrokes should not be buffered by either the typewriter software or the printer. These keystrokes include form feed, carrier return, paper down, micro down, paper up, and micro up. If these keys are buffered, the user has the unpleasant experience of holding down the appropriate key, waiting for the paper to be indexed to the correct position, then releasing the key, and watching the paper index well past the desired position. This would effectively prohibit the user from holding down these keys (using them in a typamatic fashion).
