Finisher capable of folding a paper in a z-shape when the properties of a printed image is affected

A finisher system for printing images and binding printed paper, comprising:

• a printing device which prints an image;
• a folding device which folds a printed paper into a z-shape;
• a binding device which binds a sheaf of papers into a preset size;
• and
• a control unit which determines whether an image property to be printed will be affected or not when the image is printed on the paper of the preset size, and prints the image on the paper of the preset size if it is determined that said property will not be affected, or prints the image on a paper twice as large as the preset size and folds the paper into the z-shape if it is determined that said property will be affected.

A finisher system for printing images and binding printed paper, comprising:

• an enlargement/reduction unit which enlarges or reduces an image;
• a printing device which prints an enlarged or reduced image on a paper of a preset size;
• a folding device which folds a printed paper into a Z-shape;
• a binding device which binds a sheaf of papers;
• and
• a control unit which determines whether an image property will be affected or not when a reduced image is printed on the paper of the preset size, and prints the reduced images on the paper of the preset size if it is determined that said property will not be affected, or prints the image on a paper twice as large as the preset size and folds the paper into the Z-shape if it is determined that said property will be affected.

A finisher system for binding papers after copying, comprising:

• a copying device which copies an original document;
• a folding device which folds a paper having an image copied in said copying device into a z-shape;
• a binding device which binds a sheaf of papers into a preset size;
• and
• a control unit which determines whether a document image property to be printed will be affected or not when a document image is copied on the paper of the preset size, and copies the image on the paper of the preset size if it is determined that said property will not be affected, or copies the image on a paper twice as large as the preset size and folds the paper into the z-shape if it is determined that said property will be affected.
