Abstract
An image forming apparatus includes an image data input unit; an image forming unit adapted to print an image on a printing sheet in accordance with image data from the image data input unit; a control unit connected to the image forming unit; and a billing setting unit adapted to enable to selectively set either a first mode for billing per side of the printing sheet or a second mode for billing per sheet of the printing sheet for double-sided printing, wherein the control unit executes a printing service in accordance with the set mode by the billing setting unit.
Claims9
An image forming apparatus capable of printing on both sides of a printing sheet, comprising:
- an image data input unit adapted to input image data;
- an image forming unit adapted to print an image on both sides of a printing sheet in accordance with image data input by said image data input unit;
- a billing mode setting unit adapted to selectively set either a first billing mode or a second billing mode;
- a billing unit adapted to bill for printing by said image forming unit per side of a printing sheet in a case where the first billing mode is set, and bill for printing by said image forming unit per a printing sheet in a case where the second billing mode is set;
- and
- a control unit adapted to cause said image forming unit to start printing on both sides of a printing sheet after confirming that there is a balance corresponding to bill for printing on both sides of a printing sheet both in the first billing mode and the second billing mode.
A method of controlling an image forming apparatus capable of printing on both sides of a printing sheet, comprising:
- an image data input step adapted to input image data;
- an image forming step of printing an image on both sides of a printing sheet in accordance with image data input in the image data input step;
- a billing mode setting step of selectively setting either a first billing mode or a second billing mode;
- a billing step of billing for printing in said image forming step per side of a printing sheet in a case where the first billing mode is set, and billing for printing in said image forming step per a printing sheet in a case where the second billing mode is set;
- and
- a control step of causing said image forming step to start printing on both sides of a printing sheet after confirming that there is a balance corresponding to bill for printing on both sides of a printing sheet both in the first billing mode and the second billing mode.
A control program, which is executable by a computer of an image forming apparatus capable of printing on both sides of a printing sheet, describing a method of controlling said image forming apparatus, said control program having:
- an image data input step adapted to input image data;
- an image forming step of printing an image on both sides of a printing sheet in accordance with image data input in the image data input step;
- a billing mode setting step of selectively setting either a first billing mode or a second billing mode;
- a billing step of billing for printing in said image forming step per side of a printing sheet in a case where the first billing mode is set, and billing for printing in said image forming step per a printing sheet in a case where the second billing mode is set;
- and
- a control step of causing said image forming step to start printing on both sides of a printing sheet after confirming that there is a balance corresponding to bill for printing on both sides of a printing sheet both in the first billing mode and the second billing mode.
