Abstract

PURPOSE:To switch a printer device as one form or one job as a unit by providing plural channel I/F circuits connected to plural host computers, selecting circuits, and a memory shared among selecting circuits and registering reservation information and messages in the memory. CONSTITUTION:First and second host computers share a printer device 8 with one form or one job as the unit. That is, when first and second computers 1 and 2 access the printer device 8, selecting circuits 12c and 12d are used to refer to a reservation information area of a memory 12e, and OK is reported to the first computer 1 which first issues a check command and NG is reported to the second computer 2. The first computer 1 issues an attach command for the purpose of monopolizing the printer device 8 and sends data to the device 8 to execute printing. When this printing is terminated, a detach command which permits the second computer 2 to use the printer device is issued, and the memory 12e is cleared, and reservation information is set to start printing.
