Image forming system

An image forming system comprising:

• an image forming apparatus that performs monochrome printing;
• and
• a color printer that performs color printing, the color printer being connected to the image forming apparatus, wherein
• the image forming apparatus further includes:
• a color scanner unit configured to scan an original;
• an image-data storing unit configured to store image data scanned by the color scanner unit;
• a monochrome printing unit configured to print the image data stored in the image-data storing unit with a monochrome image quality;
• and
• an operation monitoring unit configured to determine whether the monochrome printing unit is busy, and includes:
• an output-destination setting unit configured to set, when the operation monitoring unit determines that the monochrome printing unit is busy, a printout destination of page data in the color printer.

An image forming system comprising:

• an image forming apparatus that performs monochrome printing;
• and
• a color printer that performs color printing, the color printer being connected to the image forming apparatus, wherein
• the image forming apparatus includes:
• original scanning means for scanning an original;
• color determining means for determining whether a color original is included in originals scanned by the original scanning means;
• image-data storing means for storing page data scanned by the original scanning means;
• monochrome printing means for converting the page data stored in the image-data storing means into an image and printing the image with a monochrome image quality;
• operation monitoring means for determining whether the monochrome printing means is busy;
• and
• an output-destination setting unit configured to set, when the color determining means determines that a color original is included in the originals, a printout destination of page data of the color original in the color printer and set a printout destination of page data of the originals other than the color original in the monochrome printing means and, in that case, when the operation monitoring unit determines that the monochrome printing unit is busy, change the printout destination of the page data from the monochrome printing means to the color printing means.
