リと、該行メモリに現在保持されているデータの
数を保持する行メモリレンジと、前記行メモリの
データを印字ヘツドに出力を指示する印字制御部
と、印字ヘツドとを具備するシリアルプリンタに
おいて、一定時間行メモリレンジの数が増加しな
いときに前記行メモリに１行分のデータが上位装
置から既に出力されたものとみなし前記印字制御
部に出力を指令する時間監視印字指令手段を具備
することを特徴とするシリアルプリンタ。 A line memory that holds data for one line to be printed next, a line memory range that holds the number of data currently held in the line memory, and a print head that instructs the print head to output the data in the line memory. In a serial printer comprising a control unit and a print head, when the number of line memory ranges does not increase for a certain period of time, the print control unit assumes that one line of data has already been output from the host device to the line memory. 1. A serial printer comprising time monitoring printing command means for commanding output.
