Claim 5:
6. A printing control method by a printing system including: a printing device including a thermal head that prints print content on a print medium; and an information processing apparatus that controls the printing device, the printing control method comprising:
by the information processing apparatus,
detecting, from print image data from a server, a position of a control target portion including a specific portion in a print image corresponding to the print image data, when a quality of the print medium is less than a determined level;
generating printing control information for printing the control target portion; and
transmitting the print image data, the position of the control target portion, and the printing control information to the printing device,
wherein the detecting,
binarizes each pixel of pixels of the print image,
executes a morphology conversion process on each binarized pixel,
extracts a contour from the pixels after the morphology conversion process,
detects a position of the specific portion from the extracted contour, and
detects the contour as the position of the specific portion when a duty ratio between one value and other value out of two values of each pixel of the extracted contour is equal to or more than a determined duty threshold, to detect the position of the control target portion including the specific portion; and

by the printing device, executing different printing controls for the control target portion and a portion other than the control target portion based on the print image data, the position of the control target portion, and the printing control information.
