Abstract
Printing control includes determining printing dot density of print data to be supplied to a printing head, averaging the printing dot density during a predetermined period of time based on the printing dot density determined, selecting a printing speed in response to the average value of printing dot density, and controlling printing to print at the selected printing speed.
Claims10
A printing control device for a printer having printing means and spacing control means, comprising:
- printing dot density detecting means for determining printing dot density of print data to be supplied to a printing head;
- averaging means interconnected to said printing dot density detecting means for averaging the printing dot density during a predetermined period of time;
- and
- printing speed control means interconnected to said averaging means for selecting a printing speed in response to an average value of printing dot density received from said averaging means and controlling said printer to print at the selected printing speed.
A method of controlling a printer having a printing head for printing print data on a recording medium, comprising the steps of:
- determining printing dot density of the print data to be supplied to the printing head;
- averaging the printing dot density during a predetermined period of time on the basis of the printing dot density determined;
- selecting, on the basis of the averaged printing dot density, a higher printing speed for print data with a lower printing dot density, and a lower printing speed for print data with a higher printing dot density;
- and
- controlling the printer to print at the selected printing speed.
