1. A method for printing, comprising:

  • measuring a first width of a media in a printer;

    comparing, via a hardware processor of the printer, the first width of the media with a second width of a printhead within the printer, said printhead comprising a plurality of heating elements, wherein said printhead;

    has a width which spans at least the full width of the media; and

    is mounted in the printer such as to apply a pressure to said media while printing the media;

    determining by the hardware processor, based on the comparing of the first width with the second width, a variation of the pressure of the printhead across the media during the printing; and

    during the printing, adjusting for each heating element of the printhead along the first width of the media an intensity of each heating element, wherein;

    each said intensity adjustment for each heating element represents either an increase in heat or a decrease in heat, relative to a heat intensity required to generate a pixel at a uniform printhead pressure; and

    said adjustments at each heating element are configured to compensate for the variations of the pressure of the printhead across the media.
