本発明によれば、プリンタにおいては、印字素子を備えた印字ヘッドと、前記印字素子を駆動して印字を行う駆動部と、前記印字ヘッドの内部温度を検出するための温度検出部と、印字モードに対応させて、印字ヘッドの内部温度を制御するために、第１の閾値及び該第１の閾値より低い第２の閾値のうちの一方の閾値を設定する閾値設定部と、前記温度検出部によって検出された印字ヘッドの内部温度である検出温度が前記閾値設定部によって設定された閾値以上である場合に、印字ヘッドの内部温度を低くするための印字条件を設定する印字条件設定部とを有する。 According to the present invention, in a printer, a print head including a print element, a drive unit that drives the print element to perform printing, a temperature detection unit that detects an internal temperature of the print head, and a print A threshold setting unit for setting one of a first threshold and a second threshold lower than the first threshold in order to control the internal temperature of the print head in correspondence with the mode; and the temperature detection A print condition setting unit for setting a print condition for lowering the internal temperature of the print head when the detected temperature, which is the internal temperature of the print head detected by the unit, is equal to or higher than the threshold set by the threshold setting unit; Have

また、第１の閾値を設定すると、テキストデータ等のような通常の文字を形成するために作成された印字データに基づいて、例えば、連続紙等の帳票に対して高速の印字を行おうとする場合に、印字素子を駆動するための駆動素子、例えば、コイルを低い温度に維持する必要がなくなるので、コイルに電圧を印加する際の休止時間を短くすることができる。したがって、印字速度が低くならない。そして、印字データのデータ量が多かったり、ドット密度が高かったりする場合においても、プリンタのスループットが低くなることがない。 When the first threshold value is set, for example, high-speed printing is performed on a form such as continuous paper based on print data created to form normal characters such as text data. In this case, since it is not necessary to maintain the driving element for driving the printing element, for example, the coil at a low temperature, it is possible to shorten the pause time when the voltage is applied to the coil. Therefore, the printing speed does not decrease. Even when the amount of print data is large or the dot density is high, the printer throughput does not decrease.
