Image forming apparatus

A method of printing one or more images on one or more recording sheets supplied from a particular paper cassette comprising the steps of:

• A) providing a plurality of paper cassettes to store recording sheets;
• B) providing at least one first memory table to memorize a plurality of print types in a predetermined order from a highest priority to a lowest priority;
• C) providing a second memory table to memorize a plurality of comparative print types;
• D) selecting a first paper cassette that stores recording sheets suited to print an image and has a print type of possible highest priority in the respective first memory table;
• E) selecting a second paper cassette that stores recording sheets suited to print the image and has a comparative print type to be compared with the print type of the first paper cassette in the second memory table;
• F) selecting one of the first and second paper cassettes based on a predetermined criterion as an ultimate paper cassette;
• and
• G) printing the image on one or more recording sheets supplied from the ultimate paper cassette.

An apparatus for printing one or more images on one or more recording sheets supplied from a particular paper cassette comprising:

• a plurality of first means for storing recording sheets respectively;
• second means for memorizing a plurality of print types in a predetermined order from a highest priority to a lowest priority;
• third means for memorizing a plurality of comparative print types;
• and
• fourth means for selecting one first means that stores recording sheets suited to print an image and has a print type of possible highest priority in the second means;
• fifth means for selecting another first means that stores recording sheets suited to print the image and has a comparative print type to be compared with the print type of the one first means in the third means;
• sixth means for selecting one of the one and another first means based on a predetermined criterion as an ultimate first means;
• and
• seventh means for printing the image on one or more recording sheets supplied from the ultimate first means.
