Abstract: A color printing device can include a print engine, a circuit, and a processor. The print engine prints onto physical media using different color colorants. The circuit has data-processing color channels corresponding to the different color colorants. The processor receives monochromatic print jobs and transmits the received monochromatic print jobs to unused color channels of the color channels for processing in parallel. The processor can transmit the processed monochromatic print jobs to the print engine for printing.

Abstract: An information processing apparatus which has received an instruction to perform communication determines whether a server supports multi-connection communication. When the information processing apparatus determines that the server does not support multi-connection communication, the information processing apparatus performs communication by using one connection instead of using multi-connection communication.

Abstract: A printing apparatus measures a communication environment between the printing apparatus and a server. Then, based on the measured communication environment, the printing apparatus selects whether to transmit a scan image to a server by using a multi-connection communication function or to transmit the scan image to the server without using the multi-connection communication function.

Abstract: A method of diverting a hunting function of a PSTN central office switch is provided. The method diverts a hunting function in the event a channel within a hunting group is available but a call can not be completed. The method comprises detecting a status of a plurality of user channels to determine whether all user channels associated with the hunting group are in use and providing a hunting diversion message to the PSTN central office switch in response to determining that all user channels associated with the hunting group are in use. The method also comprises detecting at least one user channel associated with the hunting group is available for an inbound call and providing a hunting enable message to the PSTN central office switch in response to determining that at least one user channel associated with the hunting group is available for an inbound call.
