Patent ID: 7441860

Claim:
A print instruction device for instructing a printer comprising a temperature sensor for detecting the temperature of a predetermined portion to perform a printing operation, the print instruction device comprising: a temperature acquisition unit for acquiring the temperature detected by the temperature sensor in case a printing requirement is made; a selection instruction receiving unit for receiving a selection instruction of print continuation or print standby in case the temperature acquired by the temperature acquisition unit is equal to or higher than predetermined temperature; a print data generation unit for generating print data printable by the printer by performing color conversion processing, in which the color space of image data according to the printing requirement is converted into the color space for printing operation, by using a color conversion table for a normal state in case the temperature acquired by the temperature acquisition unit is lower than the predetermined temperature, generating print data by performing color conversion processing using the color conversion table for a high-temperature state whereby the concentration value in the color space for printing operation becomes smaller in comparison with the color conversion table for the normal state in case the selection instruction receiving unit receives an instruction of print continuation, and generating print data by performing color conversion processing using the color conversion table for the normal state after the temperature of the predetermined portion of the printer becomes lower than the predetermined temperature in case the selection instruction receiving unit receives an instruction of print standby; and a print instruction unit for instructing the printer to print the generated print data.
