A communication device having a memory for storing image data and thumbnail data is capable of transmitting the image data to an image storage unit. When the communication device transmits some of the image data stored in the memory, it erases the transmitted image data in the memory to increase an area in the memory where data can be stored. The communication device transmits to the image storage unit a search request for searching for the image data corresponding to the selected thumbnail data during browsing of the thumbnail data, and receives the image data found by searching from the image storage unit.

Rotation of drawing data is required when a page orientation specified in a document, which describes each object in a hierarchical manner in a preset format, is different from a specified medium orientation. Even under such a requirement, a printing device of the invention enables a laid-out and drawn image to be printed without any subsequent rotation. In the presence of an orientation change command given to eliminate the difference between the page orientation and the medium orientation, the printing device of the invention receives a layout command and determines a layout of each object in each page on the medium with conversion of coordinates at a preset position of the object in response to the orientation change command. In the presence of the orientation change command, the printing device of the invention receives a print command, fetches an object according to the stored layout in each page, and draws and prints the fetched object in response to the orientation change command. Even when the page orientation is different from the medium orientation, this arrangement does not require any subsequent orientation change of drawing data, which has been laid out and drawn in the specified page orientation, to generate converted drawing data corresponding to the specified medium orientation.

A real time data compression method examines whether a present read-in data point is in a predicted tolerable error range. If yes, the previous data point is deemed as redundant and is ignored and after which a new data point is read in for comparing again. When a predetermined amount of data points is continuously ignored, it means the data is steady and only the final data point of these ignored ones is recorded. Otherwise, when data is varied greatly during a period, only the total amount of these varying data points and their value are recorded so the memory capacity for storing the compressed data is saved. Furthermore, the compressed data is stored in a form of a data structure in which the compressed data are expressed by multiple blocks. The block form allows increase of the efficiency of the searching process of the compressed data.
