Abstract: The present invention embraces a method and apparatus for an efficient and economical print quality setup for thermal printers. A thermal printhead of a thermal printer constitutes multiple printhead banks. The printhead banks may be controlled by strobe signals. While configuring print quality, each of the strobe signals may operate separately with different power causing the printhead banks to operate in different configurations while printing an identical pattern. As each the banks are operating in different configuration, they each print the identical pattern with a different print quality. One print quality may be selected from the different quality patterns printed by each printhead bank on a single printed label or media. The selected quality pattern corresponds to a quality factor. The method may reduce the time to select a configuration and may reduce the amount of usage of media or labels.

Abstract: The disclosure discloses a printer includes a controller. The controller performs a first feed control process, a temperature-difference calculation process, and a first printing speed determination process. In the first feed control process, in a state where an energizing device does not perform energization to the heating element, the driving device is controlled to perform non-energization feeding while causing a thermal head to contact a print-receiving medium.
