This disclosure pertains to a communication system in which a plurality of processors and displays share a printer. Formatting of the printer is controlled by means of commands such as Set Vertical Format which contains the parameters, Maximum Print Line (MPL), Top Margin (TM), Bottom Margin (BM), and an arbitrary amount of vertical tab stops. It is desirable for the displays to be able to establish their own set of formatting parameters to accommodate screen copy printout, without requiring the processor to retransmit its format parameters with each print job. This new method allows the display to save the existing set of format parameters at the printer, to set and utilize any set of format parameters which it desires, and when finished, to restore the saved set of format parameters.
