Image forming system that ensures preview display by use of portable terminal of user and information processing terminal

An image forming system comprising:

• a portable terminal having an imaging function;
• an information processing terminal that generates print data;
• and
• an image forming apparatus that generates a printed matter based on the print data received from the information processing terminal,
• wherein the information processing terminal includes:
• a print condition accepting unit that accepts an input of a print condition;
• a preview-code generating unit that codes information necessary for a preview display of the printed matter according to the print condition accepted by the print condition accepting unit as a preview-display code when a preview display instruction is inputted in the portable terminal;
• a display unit that displays the preview-display code generated by the preview-code generating unit;
• a print-data generating unit that generates the print data according to the print condition accepted by the print condition accepting unit when a print execution instruction is inputted;
• and
• a transmitting unit that transmits the print data generated by the print-data generating unit to the image forming apparatus,
• wherein the portable terminal includes:
• an imaging unit that images the preview-display code displayed in the display unit of the information processing terminal;
• an information acquiring unit that acquires information necessary for the preview display based on the preview-display code acquired by the imaging unit;
• a preview image generating unit that generates a preview image of the printed matter according to the information acquired by the information acquiring unit;
• and
• a display unit that displays the preview image generated by the preview image generating unit,
• wherein the image forming apparatus includes:
• a receiving unit that receives the print data transmitted by the transmitting unit of the information processing terminal;
• and
• an image forming unit that prints the print data received by the receiving unit.
