Title: Photographic printer
Inventor: KURISU KAZUHIRO
IPC: B65H26/08
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To use a sheet with no waste by grasping the quantity of sheet for printing a photographic print data and then printing the data at an appropriate demagnification factor. SOLUTION: A residual printable sheet length A acquired by a residual sheet detection mechanism 5 being controlled through a control section 2 is compared with a sheet length B required for printing a print data under preset print conditions. When the residual sheet length A is shorter than the required sheet length B, the ratio of the required sheet length B to the residual sheet length A is determined and the data is printed under print conditions demagnified by the ratio thus determined. When the residual sheet length A is equal to or longer than the required sheet length B, the data is printed under set print conditions. Since printing is performed at an appropriate demagnification factor while grasping the quantity of sheet, such an inconvenience as the sheet runs out during the print operation can be eliminated.  Consequently, sheet can be used with no waste and the data can be printed in a short time without supplementing the sheet in the way of printing.
