Printer apparatus with sheet supply selecting means

A printer apparatus comprising

• a) a printer module comprising
• image forming means for forming a visible image on a print sheet,
• a plurality of sheet supply means each for supplying a print sheet to said image forming means,
• signal generating means for generating a designation signal designating one of said sheet supply means, and
• first selecting means responsive to said designation signal for selecting one of said sheet supply means designated by said designation signal,
• b) data supply means provided independently of said printer module and operative to supply to said printer module data including image data relating to the image to be formed by said image forming means and control data designating one of said sheet supply means,
• said printer module further comprising
• c) second selecting means responsive to said control data for selecting the sheet supply means designated by the control data, and
• d) control means for prohibiting operation of said first selecting means after any of said sheet supply means has been selected by said second selecting means.
