An image forming apparatus includes the following. A forming operating unit performs image forming based on image data. A data obtaining unit obtains the image data as a target of the image forming. An instruction obtaining unit obtains an operation instruction to instruct the forming operating unit to perform the image forming. An authentication receiver receives a predetermined authentication operation regarding approval of reception of the operation instruction. A hardware processor performs the image forming when a limit setting regarding a limit of reception of the operation instruction is set on the image data as the target of the image forming according to the obtained operation instruction and it is determined that the authentication receiver received the authentication operation. The instruction obtaining unit obtains a setting changing instruction to change the limit setting. The hardware processor changes the limit setting based on the obtained setting changing instruction.

An object of the present invention is to provide an image forming apparatus which can reduce the burdensome operation of installing a printer driver performed by a supervisor. To attain the object, a printer according to the present invention has the function of transmitting electronic mail to personal computers connected to a network. To the electronic mail, various data for using the printer with each of the personal computers 4A, 4B, and 4C and a printer driver for the printer are attached. Accordingly, the printer driver can be delivered without intervention of the supervisor.

A printer control system including a printer control device for controlling plural printers connected thereto via a network and providing image data transmission to plural printers by using a single bitmap memory. The printer control system provides high compression of image data when the bitmap memory is used by any of the printers thereby producing an empty area in the bitmap memory for image data transmission to other printers.
