Abstract: The present invention discloses methods to mobile printing and devices and systems thereof. The mobile printing of the present invention allows a mobile device to wirelessly discover at least one printing device, wherein such discovery may be done with or without the mobile device knowing any existence and/or capability of the printing device. Also, the mobile device may or may not be connected to a same wireless network as the printing device. The printing device of the present invention supports such printing from mobile devices.

Abstract: A printing method for printing a pixel at a gray level x on paper by a printer. The printer includes a thermal print head, which includes a heater for heating a ribbon to print pixels from gray levels 1 to m−1 on the paper, and the ribbon. The method includes: if x is not greater than a value n, heating the ribbon x times and evenly distributing the heating initiation times of the x times between the time point 0 and the time point (m*(x−1)/n) for printing the pixel at gray level x on the paper. If x is greater than the value n, heating the ribbon x times and evenly distributing the heating initiation time of the n times between the time point 0 and the time point (m*(n−1)/n) and distributing the heating initiation times of the x−n times after the heating initiation time points of the n times.
