Abstract

PURPOSE:To reduce the burden of a CPU considerably to improve the system throughput, by arbitrating automatically among respective hard copy requests from plural hard copy interfaces in a hard copy switching device. CONSTITUTION:In respect to hard copy requests from plural hard copy interfaces 12-15, the request acceptance and the switching connection between accepted hard copy interfaces 12-15 and available hard copies 16 and 16' are performed automatically in a hard copy switching device 21 efficiently. Consequently, CPUs 1 and 2 only issue the hard copy request to corresponding CRT controllers 8 and 9 and CRT controllers 10 and 11, and thus, the burden of CPUs 1 and 2 is reduced.
