The operation of a printer attached to a word processor is controlled by commands from the word processor. Each printer command takes a certain amount of time for the printer hardware to process. The response time of the printer could be improved if the number of commands to the printer could be reduced. A solution to this problem is to combine like keystrokes in an interactive environment. This process has been implemented for a word processor in the Echo Mode, as shown in the figure. According to this process, the input data stream which is to be printed is scanned. Similar commands, such as those produced by consecutive nongraphic operations, are combined. The total displacement is then sent to the printer as one command.
