Printing apparatus to determine correction on suspended image data

摘要

A printing apparatus comprising: a printing unit configured to print an image based on expanded data; a measuring unit configured to measure a deviation amount of at least one of a position and a density of the image printed by the printing unit when a correction execution condition is satisfied; an expanding unit configured to expand print data based on the measurement by the measuring unit, so as to produce the expanded data; and a control unit, wherein when the correction execution condition is satisfied during the expanding of current print data which corresponds to a current page being expanded, the control unit is configured to control the expanding unit to suspend the expanding of the current print data, the measuring unit to measure the deviation amount, and the expanding unit to restart expanding an unexpanded portion of the current print data based on the measurement.

1. A printing apparatus comprising:
a printing section configured to print an image based on expanded data; and a control device configured to:
measure a deviation amount of at least one of a position and a density of the image printed by the printing section when a correction execution condition is satisfied; andexpand print data based on the measured deviation amount so as to produce the expanded data,wherein when the correction execution condition is satisfied during the expanding of current print data which corresponds to a current page being expanded, the control device is configured to suspend the expanding of the current page being expanded so that an unexpanded portion of the current page remains, measure the deviation amount, and restart expanding the unexpanded portion of the current page based on the measurement performed after the expanding is suspended, andwherein the expanded data is generated by analyzing the print data, generating intermediate data based on the print data, and expanding the intermediate data while adjusting the intermediate data based on the measured deviation amount.
