Print system and print control method

Abstract

To display a print preview to which an operating instruction from an operation panel provided for an external operating apparatus, an interruption event which is transferred from the external operating apparatus 111 to a host computer 101 is detected every instruction of the operation panel provided for the external operating apparatus 111, image data which is read out from a memory card which can be loaded into the external operating apparatus 111 and a print setting which is set are obtained in accordance with the detected interruption event, and a preview display unit 305 controls a print preview display in which the print setting has been reflected to a display device of the host computer 101 and an updating display of the print preview display.

Description

technical field [0001] The present invention relates to control of a printing system in which an external operating device, a printer, and a host computer each having a communication interface for transmitting and receiving information in real time are communicably connected via an interrupt control signal and a printer driver. Background technique [0002] Conventionally, when a printer is used to print digital images taken by a digital camera, etc., a method of browsing, editing, and printing the digital images with software on the PC is generally used after saving the digital images to the hard disk of the PC. [0003] Also among recent printers, there is a printer having an insertion slot for inserting a recording medium used in a digital camera or the like and an operation panel for receiving an instruction of print setting from a user, and having a A single printer connected to a PC to print the digital image in the recording medium. [0004] In some of these printers...

Problems solved by technology

[0005] However, in the conventional general printing method via the host PC, it is necessary to operate the software on the PC along with the operation of the mouse and keyboard, and it is difficult to always print easily.

[0006] In addition, in the case of a printer with a plug-in slot and an operation panel, the operation is easy, but due to the miniaturization of the display on the operation panel and the dedicated monitor, there is a problem that it is difficult to perform print settings and image browsing.

Furthermore, since this operation is performed by the printer alone during printing, resources such as the CPU and memory of the printer are very costly, and sometimes its printing speed and printing quality are inferior to those of printing via the host computer.
