AI Technical Summary

Technical Problem

Conventional printers experience variations in printing density due to frequent switching of density correction data when the environmental temperature fluctuates near the boundary line, leading to inconsistencies in print quality, especially during large printing jobs.

Method used

A printer with a temperature sensor and a control unit that applies different setting information based on distinct thresholds for ambient temperature, using first and second setting information when the temperature is above or below specific thresholds, and includes a mechanism to prevent frequent switching of these settings.

Benefits of technology

This approach reduces variations in print density by stabilizing the printing settings, ensuring consistent print quality even with fluctuations in ambient temperature.

Abstract

This reduces variations in print density even when the printer's ambient temperature fluctuates. [Solution] A printer according to one aspect of the present invention includes a temperature sensor for detecting the ambient temperature of the printer, a thermal head for printing information on a printing medium, a storage unit for storing first setting information and second setting information corresponding to the case when the ambient temperature is lower than the first setting information as setting information related to print density, and a control unit for applying either the first setting information or the second setting information to printing by the thermal head. The threshold values ​​for ambient temperature are different: a first threshold for applying the first setting information and a second threshold for applying the second setting information.
