Printing Speed Mode Selection
This printer is designed to control the printing speed according to the power supply voltage
and printhead temperature. When the power supply voltage drops to the limit, the printer
stops printing, then resumes the job at a slower speed to print the remaining data for the
line. When the printhead temperature rises to the limit, the printer stops printing. Then it
resumes printing at a slower speed if the printhead temperature recovers to the specified
level. The printing speed mode is determined according to the flowchart shown in Page 1-6.
