Abstract:
1. A print system comprising an external operating apparatus, a host computer which communicates with said external operating apparatus, and a printer which communicates with said host computer, wherein said external operating apparatus comprises: reading means for reading out image data from a detachable storage medium; a display unit which displays a print setting screen; an operation panel which is operative to set print settings in accordance with a print setting instruction provided by a user based on the print setting screen displayed on said display unit; a button operative to instruct said host computer to preview the image data read out by said reading means; transmission means for transmitting the image data read out by said reading means, to said host computer in response to said button being operated; and a controller which generates a plurality of interruption events including a print setting information interruption event for causing said host computer to set therein the print settings of the image data transmitted by said transmission means, the print setting information interruption event being generated in accordance with said operation panel setting the print settings after the image data read out by said reading means is transmitted to said host computer by said transmission means so that the generated print setting information interruption event includes the print settings set by said operation panel and is transmitted to said host computer, wherein said host computer comprises: a receiving unit which receives the image data read out by said reading means and then transmitted by said transmission means from said storage medium, and receives the plurality of interruption events generated by said controller from said external operating apparatus; a control unit which detects whether the interruption event received by said receiving unit is the print setting information interruption event, and controls print preview display such that the print settings included in the received print setting information interruption event are reflected in the image data received by said receiving unit, every time the print setting information interruption event is detected; and a print control unit which generates print data corresponding to the print settings included in the received print setting information interruption event, wherein said printer prints the print data output from said host computer, and wherein the print settings reflected in the print preview display are the same print settings used to generate print data.
