Abstract

In certain word processor applications, there is a need to provide logging of multiple interactive tasks. In particular, when the word processor is connected to a host central processing unit and operated in a data processing mode, it is often important to track operator responses to system messages. Typically, however, there is only one printer available. A problem is therefore presented as to how to track operator keystrokes and system responses on a hard copy printer, preferably with immediate system turnaround. The solution to this problem uses the Echo mode printer access method to allow multiple asynchronous tasks to add data to a FIFO (first-in, first-out) queue of printer work. This is a new use of existing software, and no changes to the printer software are required.
