Printer control device.

摘要

A printer control device (2) is connected between the output of one or more word processing terminals (12) and the input to a printer (16). The device (2) is also connected to an envelope printer (22) and/or a label printer (21). The device functions to recognise printable control codes inserted into a document text while it is being composed by a word processor operator to identify the beginning and end of address data in a letter. The device controls printing of this address data on envelopes or labels while the letter itself is being printed on the main printer (16).
