Abstract

PURPOSE:To allow processors to effectively use printers, by connecting a plurality of processors and a plurality of printers by a data loop. CONSTITUTION:The first - fifth processors 1-5 are operated as host computers and respectively use the first - seventh printers 11-17 as output devices. By connecting the first - fifth processors 1-5 and the first - seventh printers 11-17 by a data loop 21 to control them, all of the processors 1-5 can use all of the printers 11-17.

複数の印刷装置は、複数のプロセサの出力装置として動
作し、複数のプロセサの出力により。Multiple printing devices act as output devices for multiple processors and by outputting from multiple processors.

印刷を実行するためのものである。This is for executing printing.

データループは、複数０プｐセサおよび複数の印刷装置

ての印刷装置１１〜１７を使用することができる。FIG. 1 is a block diagram showing an embodiment of a printing method according to the present invention 1111. In FIG. 1, 1 to 5 are the first to fifth processors, respectively, and ll to 17 are the first to fifth processors, respectively.
The seventh printing device, 21, is data loose. The first to fifth processors 1 to 5 are operated as host computers, and the first to seventh printing devices 11 to 17 are operated as output devices, respectively.
use. By controlling the connection between the first to fifth processors 1 to 5 and the first to seventh printing devices 11 to 17 using the data loop 21, all the processors 1 to 5 can connect all the printing devices 11 to 17. can be used.

とができる。In one family, the first processor 1 uses the first printing device 11 as an output device, and similarly, the fifth processor 5 uses the fifth printing device 11 as an output device.
It is assumed that the printing device 15 is used as an output device and the system is operated. The sixth and seventh printing devices 16 and 17 are unused. If the output of the first processor l increases and the output of the first printing device 11 cannot keep up, the first processor l can use the sixth and seventh printing devices 16 and 17 simultaneously as output devices. can.

Firstly, when the processor uses a printing device, it has the effect of dynamically increasing the number of printing devices used if the printing device becomes a bottleneck, and secondly, it can switch the connection between the processor and the printing device. This has the effect that a switching device for performing the above is not required, and the third effect is that the overall number of printing devices can be reduced.
