Abstract: A virtual computer system includes a first saving unit that saves at least one or more snapshots each having recorded therein a state of a virtual machine, the state including an application program installed on the virtual machine, the snapshot being saved as a reference snapshot; an applying unit that applies the reference snapshot to the virtual machine when an execution request for the application program is received; and a second saving unit that saves a state of the virtual machine that executes the application program, the state being saved as a snapshot.

Abstract: An image processing apparatus includes a detection unit and a determination unit. The detection unit detects an error by comparing image data related to a print job with read image data obtained as a result of reading a print output related to the print job. The determination unit compares read image data related to a post-error print output, which is a continuously-printed print output related to the print job for a page subsequent to a page in which the error is detected, with the image data when the error is detected by the detection unit, so as to determine a process for recovering the print job by using the post-error print output.

Abstract: An information processing apparatus includes an extracting unit that extracts features of printing operations of a user, and a measurement unit that measures a processing throughput of executing the printing operations of the user as a substitute for a printing operation as a predetermined standard if a feature of the printing operation serving as the standard matches the features extracted by the extracting unit.

Abstract: An image processing apparatus includes: an accepting unit that accepts an image forming instruction; a forming image generating unit that generates plural forming processing images corresponding to respective plural image forming devices on the basis of the accepted image forming instruction; and an output unit that outputs the plural forming processing images to the corresponding image forming devices.
