摘要:
A printing apparatus in which a general command is converted to a real-time command depending on the needs, allowing fast status analysis and error recovery with fewer number of control commands without inconveniencing the user, a control method therefor, and a data processing apparatus using the printing apparatus. In the printing apparatus or the data processing apparatus including the same which is operated by transmission of command data and print data from a host computer, general data usually processed in order is converted to a real-time command using a real-time command identifier. The printing apparatus receives the data with the real-time command identifier and processes the command or print data designated by the real-time command identifier. The apparatus and method allow using a fewer number of commands to execute various controls.

Disclosed is a printing apparatus including a priority identifier establishment unit. More particularly, the printing apparatus, processing an instruction designated by a priority identifier before another instruction, includes the priority identifier establishment unit that allows a priority identifier to be designated in various forms and methods. Since the priority identifier can be established in various forms and methods, the printing apparatus can achieve enhanced flexibility and effect in priority processing.
摘要:
There are provided a printing apparatus and a method for processing real-time commands using the same. The printing apparatus is able to be stably operated without any mechanical troubles such as degraded performance of the printing apparatus, which are caused when real-time commands are analyzed and processed on a receive interrupt routine, by detecting real-time commands from data transmitted from the host computer, separately storing the detected real-time commands in a real-time command buffer and processing the stored real-time commands in preference to the other data.

There is provided a printing method including: receiving at least one of print data and control commands from a host device; storing print image data on the basis of the received print data when there is no previously stored print image data before the receiving of the print data, and storing print image data on the basis of the received print data after deleting previously stored print image data when there is the previously stored print image data before the receiving of the print data; and printing the stored print image data according to a preset control command among the control commands received from the host device.
摘要:
A method for processing an image in a printer, which can effectively carry out a conversion operation by comparing quantities of light components for R (Red), G (Green) and B (Blue) associated with each pixel to be converted when a two or more-color image is converted into a two-color image, and can decide conversion colors by applying a regular rule to all possible cases when the conversion colors are decided, such that an excellent conversion result can be achieved. In the method, a primary color and a secondary color are set as printable colors in the printer and an original image is inputted. Color difference values associated with the primary color, the secondary color and a white color are produced on an original image pixel-by-pixel basis, and a corresponding pixel color of the original image is converted into the primary, secondary or white color associated with a smallest color difference value.
