Printing device with manual paper feeding function

A printing device with a manual paper feeding function, comprising:

• a manual paper feeding unit;
• a first paper size input unit that inputs an input paper size of the manual paper feeding unit by an operation;
• a second paper size input unit that detects a detected paper size of fed paper and inputs the detected paper size;
• a determining unit that determines, when the input paper size is input by the first paper size input unit, whether the detected paper size input by the second paper size input unit corresponds with the input paper size;
• an inquiring unit that inquires on a display whether to fix the paper size to the detected paper size when the determining unit determines that the detected paper size does not correspond with the input paper size;
• a paper size fixing unit that fixes the paper size when the determining unit determines that the detected paper size does not correspond with the input paper size, in accordance with a response to the inquiry on the display;
• a paper size fixing unit that fixes the paper size when the determining unit determines that the detected paper size corresponds with the input paper size;
• and
• a sensor unit,
• wherein, when the input paper size has not been input by the first paper size input unit and the detected paper size is a nonstandard paper size, the sensor unit senses whether the manual paper feeding unit has been opened and the printing device carries out a printing process on each fed paper so long as the detected paper size is within a predetermined range.

A method for manually feeding paper, comprising:

• feeding paper;
• providing an option to input an input paper size of the fed paper by an operation;
• detecting a detected paper size of fed paper and inputting the detected paper size;
• determining, when the input paper size is input by the operation, whether the detected paper size corresponds with the input paper size;
• inquiring on a display whether to fix the paper size to the detected paper size when it is determined that the detected paper size does not correspond with the input paper size;
• fixing the paper size when it is determined that the detected paper size does not correspond with the input paper size, in accordance with a response to the inquiry on the display;
• fixing the paper size when it is determined that the detected paper size corresponds with the input paper size, and
• when the input paper size has not been input and the detected paper size is a nonstandard paper size, sensing whether the paper has been manually fed and carrying out a printing process on each fed paper so long as the detected paper size is within a predetermined range.
