Information processor, printing apparatus, information processing system, printing method and printing program
A print output apparatus, etc., designed to effectively increase the speed of printing started when the apparatus is in a sleep state. Before print data is transferred to the print output apparatus, a first command for making the print output apparatus to execute processing for shifting from the sleep state to a standby state and a second command to stop calibration processing are sent to the print output apparatus.
1. An information processor which transfers print data to a printing apparatus having a standby state in which printing can be performed, and a sleep state of low power consumption in which printing cannot be performed, said information processor comprising:
a display unit adapted to display a print setting screen for setting print settings;
a first command output unit adapted to in response to displaying of the print setting screen, output to the printing apparatus a first command to make the printing apparatus execute shift processing for shifting from the sleep state to the standby state, the first command being output after displaying the print setting screen by the display unit and before an issuance of an instruction to perform printing; and
a print data output unit adapted to output the print data, which is related to the print settings, to the printing apparatus in response to the issuance of the instruction to perform printing.
2. An information processor according to claim 1 , further comprising a second command output unit adapted to output to the printing apparatus a second command to stop calibration processing, which is executed in the shift processing, after outputting of the first command and before outputting of the print data, if a black-and-white print setting is set as the print settings.
3. A printing method for an information processor which transfers print data to a printing apparatus having a standby state in which printing can be performed, and a sleep state of low power consumption in which printing cannot be performed, said method comprising the steps of:
displaying on a display unit of said information processor a print setting screen for setting print settings;
outputting to the printing apparatus a first command in response to displaying of the print setting screen, to make the printing apparatus execute shift processing for shifting from the sleep state to the standby state, the first command being output after displaying the print setting screen by the display unit and before an issuance of an instruction to perform printing; and
outputting the print data, which is related to the print settings, to the printing apparatus in response to the issuance of the instruction to perform printing.
4. A printing method according to claim 3 , further comprising the step of outputting to the printing apparatus a second command to stop calibration processing, which is executed in the shift processing, after outputting of the first command and before outputting of the print data, if a black-and-white print setting is set as the print settings.
5. A computer-readable medium on which is stored a computer-executable program for an information processor which transfers print data to a printing apparatus having a standby state in which printing can be performed, and a sleep state of low power consumption in which printing cannot be performed, said printing program enabling a computer to execute the steps of:
displaying on a display unit of said information processor a print setting screen for setting print settings;
outputting to the printing apparatus a first command in response to displaying of the print setting screen, to make the printing apparatus execute shift processing for shifting from the sleep state to the standby state, the first command being output after displaying the print setting screen by the display unit and before an issuance of an instruction to perform printing; and
outputting the print data, which is related to the print settings, to the printing apparatus in response to the issuance of the instruction to perform printing.
6. A computer-readable medium according to claim 5 , further comprising the step of outputting to the printing apparatus a second command to stop calibration processing, which is executed in the shift processing, after outputting of the first command and before outputting of the print data, if a black-and-white print setting is set as the print settings.
