Embodiments of the invention generally relate to the printing of an image. In one version, first image data representing a first background image of a first size is stored in a memory. A printing apparatus is connected via a network to a server that stores second image data representing a second background image of a second size that is greater than the first size. A condition for printing is set based on image data representing an image to be printed. Based on the set condition, the image data representing the image to be printed is synthesized with the first image data representing the background image that is stored in the memory or the second image data obtained from the server by accessing the server via the network. Printing is performed based on the synthesized image data.

Printing apparatus and printing method

In a communication apparatus corresponding to an analog communication path of a voice band and a network communication path, high-speed and high-reliability data communication are performed by selecting an appropriate communication path without troublesome user operation. A communication apparatus which performs IP communication and analog communication via an ADSL gateway obtains the IP address of a destination station from an SIP proxy server and transmits/receives communication data to/from the destination station on an IP network by a file transmit/receive protocol such as FTP, HTTP or the like, when the telephone number of the destination station corresponds to a VoIP network. The apparatus performs analog facsimile communication on a line switching network when the telephone number of the destination station does not correspond to the VoIP network. The apparatus performs the analog facsimile communication on the VoIP network or the line switching network when the destination station corresponds to the VoIP network but does not have any digital communication means.
