Abstract
A method for printing includes analyzing print quality requirements for a printing area; adjusting settings for heater elements (e.g., energy and/or firing durations) of strobe lines based on the requirements analysis; and providing a plurality of individual strobe signals to the strobe lines. The strobe signals can be transmitted simultaneously, for example with a field-programmable gate array. Analyzing print quality requirements can include separating the printing area into one or more areas of interest, such as rows and/or columns. For each area of interest individual print quality settings (e.g., darkness, contrast, and/or media sensitivity) may be selected.
Claims20
A method comprising:
- grouping one or more regions of interest (ROIs) associated with an image into one or more region of interest (ROI) groups;
- and
- determining one or more print quality settings for each of the one or more ROI groups based at least in part on one or more printing requirements associated with each of the one or more ROIs to compensate for print quality variation along a width of a label on which the image is to be printed.
A printer comprising:
- a thermal printhead comprising one or more thermal printhead heater elements;
- and
- a driver circuit communicatively coupled to the thermal printhead and configured to:
- group one or more regions of interest (ROIs) associated with an image into one or more region of interest (ROI) groups;
- and
- determine one or more print quality settings for each of the one or more ROI groups based at least in part on one or more printing requirements associated with the one or more ROIs to compensate for print quality variation along a width of a label on which the image is to be printed.
