In a communication system of the present invention, second setting information is automatically generated according to first setting information used for performing predetermined processing between at least two devices when the first setting information is set to a first device of the at least two devices, where the second setting information is generated for a second device of the at least two devices. Then, the communication system transmits the automatically-generated second setting information to the second device. Otherwise, the communication system writes the automatically-generated second setting information onto a portable recording medium so that the second device can read the second setting information from the portable recording medium.

Network configuration setting generation system, device, and method

An information processing apparatus encrypts data that is to be printed by a printing apparatus and stored in a storage device detachably connected to the information processing apparatus so that the encrypted data can be decrypted by the printing apparatus. Once the data has been encrypted, the information processing apparatus stores the encrypted data in the storage device. After the storage device including the encrypted data has been detached from the information processing apparatus and connected to the printing apparatus, the printing apparatus decrypts the encrypted data stored in the storage device and executes a printing process according to the decrypted data.

Printing system, information processing apparatus, printing apparatus, print management method, and storage medium

A printing system has a printing apparatus and a host apparatus. Print data or control data is transferred between the printing apparatus and the host apparatus in accordance with at least two transfer methods. Upon detecting that a specific state has passed, the printing apparatus or the host apparatus predicts a change of the transfer method when (or immediately after) the specific state has passed. An analysis is conducted to determine whether the transfer method has been changed for the data subsequently transferred. If it is found that the transfer method used in the printing apparatus or the host apparatus has been changed, the other apparatus accordingly changes the transfer method. On the other hand, if the transferred data is based on the currently used method, the method is not changed, but is maintained.

Printing system and printing apparatus

A printing system includes a host computer and a printer. The host computer includes a memory which store process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (,) to divide encoded image data in a page of encoded image data into blocks, each block having a size which is less than a storage capacity of a buffer on a printer, and (,) to transmit the blocks of encoded image data to the printer. The printer includes a memory which stores process steps that are executable by a processor, and a processor. The processor executes the process steps stored in the memory (,) to store a predetermined amount of encoded image data in a buffer, (,) to control a printer engine to print images based on the encoded image data stored in the buffer, and (,) to store additional encoded image data, including blocks of the encoded image data, in the buffer in place of the encoded image data for which images have been printed.

Printing system for dividing a page into blocks

When a host computer makes a printer print a document, the driver on the host computer sends character codes of characters that appear for the first time in that document and corresponding character images to the printer in advance, and registers them. After this process, the driver transmits, to the printer, characters in the document to be printed as character codes, and data other than characters as mapped image. The printer maps an image on a page memory, maps characters as images with reference to the registered character codes and character image, and superposes the mapped character images on the image mapped on the page buffer. The printer prints the image on paper. The printer can divide an image into bands, and can map the image in units of bands, in place of pages. With this arrangement, the memory capacity can be reduced, and bands having identical contents or blank bands can be processed as codes.
