摘要 PURPOSE:To prevent a red line from converting to a black line and said line from subjected to thermal recording by recording a red thin-line image on a sheet with emphasis. CONSTITUTION:A screen 12 written and recorded by handwriting is turned and a thermal head 7 is driven based on image information reading the write recording on the screen 12 to attain 2-color recording. A control means is provided, which records the red thin-line written on the screen 12 with emphasis processing. Much energy is applied to the thermal head 7 with respect to initial several lines (e.g., 16 lines) in advance. Thus, it is prevented that the red print is converted into a black print at several tens line at the start of the print.
