Printer with touch panel for receiving contact trajectory pattern for producing a print

A printer, comprising:

• a feeder configured to feed a medium to be printed;
• a print head configured to form desired print on said medium to be printed fed by said feeder and producing a print;
• a housing that constitutes an outer shell of the printer and incorporates said feeder and said print head;
• a discharge port disposed on one side of said housing and configured to discharge said print produced by said print head to the outside of said housing;
• a display portion disposed on said housing and configured to display a print image expressing print contents of said print to be produced;
• an operation portion disposed above said display portion and capable of receiving an operation input in a state where a display on the display portion can be seen through the operation portion;
• a detecting device configured to detect said operation input through contact to said operation portion;
• a first trajectory determining portion configured to determine whether or not a contact trajectory with a first predetermined pattern along a first direction toward said discharge port side has been input in a state where said print image is displayed on said display portion on the basis of a detection result of said detecting device;
• and
• a printing control portion configured to control said feeder and said print head when it is determined by said first trajectory determining portion that the contact trajectory with said first predetermined pattern has been input so as to produce said print corresponding to said print image displayed on said display portion and to discharge the print from said discharge port.
