Print control apparatus indicating appropriate paper cassette for printing and method of same

A print controller for controlling a printing unit having a plurality of paper cassettes and capable of printing with a predetermined process on a recording medium, comprising:

• judgement means for judging a print mode specified by print data from an external apparatus;
• recording medium type storing means for storing what type of recording medium is mounted on each of the paper cassettes;
• paper cassette selecting means for displaying substitute paper cassettes to cause a user to select one of the displayed paper cassettes when detecting that the recording medium in the current paper cassette runs out;
• process executable/nonexecutable determination means for determining whether the predetermined process is executable on the recording medium mounted on each of the paper cassettes on the basis of the information obtained from said recording medium type storing means and the print mode judged by said judgement means;
• and
• display control means for displaying paper cassettes having a recording medium on which the predetermined process is determined to be executable or nonexecutable by said process executable/nonexecutable determination means so as to be discriminated from each other on said paper cassette selecting means.

A print control method for controlling a printing unit having a plurality of paper cassettes and capable of printing with a predetermined process on a recording medium, comprising:

• a judgement step of judging a print mode specified by print data from an external apparatus;
• a paper cassette selecting step of causing a user to select a substitute paper cassette when detecting that the recording medium in the current paper cassette runs out in printing the print data;
• a process executable/nonexecutable determination step of determining whether the predetermined process is executable on the recording medium mounted on each of the paper cassettes on the basis of the information read from a recording medium type storing unit containing information on what type of recording medium is mounted on each of the paper cassettes and the print mode judged in said judgement step;
• and
• a control step of causing, in said paper cassette selecting step, a user to select only the paper cassette having a recording medium on which the predetermined process is determined to be executable in said process executable/nonexecutable determination step.
