An image forming apparatus includes a hot folder storage region, an image forming device, and a hot folder controller that decides whether a second resource file, having the same content as a first resource file, is stored in the hot folder storage region, when a first image forming job is submitted to the hot folder, stores the first resource file in the sub folder, and causes the image forming device to form the image on a medium, using the first control file and the first resource file, when the second resource file is not stored, and stores, when the second resource file is stored, a link file indicating a path to the second resource file in the sub folder, acquires the second resource file using the path, and causes the image forming device to form the image on the medium, using the first control file and the second resource file.

A resource service system is one of a plurality of resource service systems each capable of communicating with a reception service system that receives data from a plurality of clients. The resource service system acquires data from a first queue that receives and stores data transmitted from the reception service system, and processes the acquired data. In a case where it is determined a number of pieces of data of a predetermined client transmitted from the reception service system per unit time exceeds a first predetermined number, the resource service system sets a first setting for preventing the reception service system from transmitting the data of the predetermined client to the first queue.

A printing system includes a plurality of image forming apparatuses capable of mutually communicating with a portable terminal device and a client terminal device. The client terminal device generates a print job that includes print data and job information. The portable terminal device stores job information transmitted from the client terminal device. The image forming apparatus acquires the job information from the portable terminal device, acquires the print data corresponding to the job information from the client terminal device, and execute image output the print data.

An information processing apparatus includes a printer driver configured to generate a print command compliant with a predetermined printing protocol based on print data obtained from a data generation application, one or more extension modules configured to generate a print command compliant with another printing protocol different from the predetermined printing protocol, a storage unit configured to store information associating the one or more extension modules to be used for generating the print command compliant with said another printing protocol with the printer driver, and an output unit configured to output the print command compliant with said another printing protocol, the print command being obtained through processing of the print data obtained by the printer driver, and the processing being performed by the one or more modules indicated by the information.

Examples disclosed herein relate to determining whether a stored print job is potentially orphaned, and, in response to determining that the stored print job is potentially orphaned, requesting a renewal from a user associated with the stored print job and deleting the stored print job if no renewal is received within a configurable time period.

A communication system includes an information terminal, and a printing apparatus configured to perform intergroup communication with the information terminal belonging to a group. The printing apparatus includes a printing part configured to perform printing, a data receiver configured to receive print data from the information terminal via the intergroup communication, and a print controller configured to control the printing part using the received print data.

An image processing device may include a controller configured to, in a case where a disabling instruction to cause a service state to shift to a disabled state is obtained under a situation where the service state is an enabled state, shift the service state from the enabled state to the disabled state, and in the case where the disabling instruction is obtained under the situation where the service state is the enabled state, send an acceptance stop instruction to a server. The acceptance stop instruction may be an instruction to cause the server to stop acceptance of a job sending request.

An image forming apparatus includes a memory, a control device, and an image forming device. The control device includes a processor and functions as a memory manager and a controller through the processor executing a control program. The memory manager allocates amounts of the memory depending on different types of processing constituting a job to create a plurality of memory regions. The controller executes the job using at least one of the plurality of memory regions. The image forming device executes an image forming job of forming an image on a sheet under control of the controller.

A varied least recently used (VLRU) caching technique is used to enable print data to be available at a cache of a client for printing, even after an agent performs a deletion of a hash value for the print data at a cache of the agent. The deletion of the print data (cached at the cache of the client) is postponed at the client device via the use of a waiting list, so that the cached print data can be printed at a physical printer of the client, in response to receiving a delayed print job from the agent that specifies the hash value as a result of a deduplication process performed by the agent.

An image processing device may include a controller configured to, in a case where a disabling instruction to cause a service state to shift to a disabled state is obtained under a situation where the service state is an enabled state, shift the service state from the enabled state to the disabled state, and in the case where the disabling instruction is obtained under the situation where the service state is the enabled state, send a first event deletion instruction to a server. The first event deletion instruction may be an instruction to delete, from an event which is to be notified to the image processing device, an acceptance of a job sending request by the server.
