Title: Image forming device
Inventor: SHUDA TOMOHIRO
IPC: B41J5/30
Filed: 2001-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device in which confidentiality is insured by controlling the start of a printing output for a printing request from a plurality of host devices. SOLUTION: When a host computer requests printing through a network and a privacy protective setting is set to be ON, a laser printer stops a transmission of data from the host computer in a state of an output reservation and enters into a stand-by state for waiting permission of the output. When a permission key in an operation section is pushed down and the output is permitted, the host computer re-starts the data transmission. An engine carries out printing based on printing data received from the host computer. Thus, operation for the output of printing can be started after a user of the host computer has arrived at the location of the laser printer, which prevents a recorded paper having an outputted record from meeting other people's eyes or being taken away by mistake, thereby insuring confidentiality.
