摘要： A printer buffer system for connecting a number of personal computers and a number of printers includes a master printer buffer and one or more slave buffers, forming an expandable printer buffer system. Each buffer includes an input storage device for storing data, command and status signals from a personal computer or for controlling the transfer of data between the computer and the buffer as well as output storage devices for storing status, command and data signals for the transfer of data between the printer and the buffer and for controlling such transfer. Personal computers and printers may be added or removed from the system at will and the user may select a designated printer.
