US 9,959,489 B2 · Network system, printing device, and control method of a printing device

Abstract

Delaying processing based on received commands is suppressed while preventing executing parallel processes involving operation of hardware. Servers can send printing commands and non-printing commands to a printing device. When a printing command is received from a first server and a printing command is then received from another server different from the first server while a process based on the printing command received from the first server is executing, the printing device does not execute the process based on the printing command received from the other server; but if a non-printing command is received from another server, the printing device executes a process based on the non-printing command received from the other server parallel to the process based on the printing command received from the first server.

Dependent claims

A network system comprising:

a plurality of servers including a first processor;
and
a printing device, connected through a network to the plurality of servers, including a second processor and configured to print to recording media connected through a network, wherein:
the first processor of the servers is configured to transmit a first command belonging to a first command group instructing executing a process involving operation of hardware in the printing device, or a second command belonging to a second command group instructing executing a process not involving operation of hardware in the printing device, and
when the printing device receives a first command from one server and is executing a process based on the received first command, the second processor of the printing device is configured to:
not execute a process based on a first command received from another server that is different from the one server, but
execute, when a second command is received from another server that is different from the one server, the process based on the received second command parallel to the process based on the first command received from the one server.

4 more elements

A printing device configured to connect through a network to multiple servers, and comprising:

a processor;
and
memory,
wherein the processor is configured to:
communicate with the servers,
execute a process based on a first command belonging to a first command group instructing executing a process involving operation of hardware when the first command is received from one server,
not execute a process based on a first command received from another server different from the one server when the first command is received from another server different from the one server while executing the process based on the first command received from the one server, and
execute a process based on a second command belonging to a second command group instructing executing a process not involving operation of hardware when the second command is received from another server different from the one server while executing the process based on the first command received from the one server.

5 more elements

A control method of a printing device that connects through a network to multiple servers, comprising

when a first command belonging to a first command group instructing executing a process involving operation of hardware is received from one server and a process is executed based on the received first command, not executing, by a processor of the printing device, a process based on a first command received from another server different from the one server, and
executing, by the processor of the printing device, a process based on a received second command when a second command belonging to a second command group instructing executing a process not involving operation of hardware is received from another server different from the one server, while executing the process based on the first command received from the one server.
