Abstract
A printer according to an embodiment includes a communication interface that receives print data from an external device. A print head prints on a sheet, line by line according to the received print data. A motor drives a roller to transport the sheet, line by line according to the received print data. A processor configured determines, for a current print line, a target transport speed for transporting the sheet, and determines one or more intermediate speeds defined in advance and between a current transport speed of transporting the sheet and the target transport speed. The processor controls the motor to transport the sheet at each determined intermediate speed and the target transport speed, sequentially.
Claims20
A printer comprising:
- a communication interface configured to receive print data from an external device;
- a print head configured to print on a sheet, line by line according to the received print data;
- a motor configured to drive a roller to transport the sheet, line by line according to the received print data;
- and
- a processor configured to:
- determine, for a current print line, a target transport speed for transporting the sheet,
- determine one or more intermediate speeds defined in advance and between a current transport speed of transporting the sheet and the target transport speed, and
- control the motor to transport the sheet at each determined intermediate speed and the target transport speed, sequentially.
A method of controlling a transport speed of a printer, the method comprising:
- receiving print data from an external device;
- determining, for a current print line to be printed on a sheet by a print head, a target transport speed for transporting the sheet;
- determining one or more intermediate speeds defined in advance and between a current transport speed of transporting the sheet and the target transport speed;
- and
- controlling a motor to transport the sheet at each determined intermediate speed and the target transport speed, sequentially.
