Patent number: 8830532Abstract: A printing control method of a printer is implemented in a printing system including an information providing device and a printer. The printer is connected to the information providing device for printing data sent by the information providing device. Once a printing driver program of the information providing device receives page data to be outputted, the printing driver program converts a number of first color components of the page data into a number of second color components and checks if any one of the second color components contains zeroes for all the content. If one second color component is found to have zeroes for all the content, this very second color component will not be sent to the printer, whereas the rest of the second color components will be sent to the printer for output.Type: GrantFiled: January 6, 2013Date of Patent: September 9, 2014Assignee: Aetas Technology IncorporatedInventor: Chun-Yu Chang

Patent number: 8482589Abstract: A light emitting control device for a light emitting diode print head includes a control unit, a pulse-mask unit, a strobe unit and a data output unit. The pulse-mask unit outputs n clock signals in sequence to a light emitting diode print head. The strobe unit outputs a strobe signal to the light emitting diode print head, so as to switch on the light emitting diode print head. The data output unit outputs a print data signal to the light emitting diode print head. When the pulse-mask unit outputs a k-th clock signal of the n clock signals, the pulse-mask unit delays the k-th clock signal for a predetermined time, and the data output unit pauses outputting the print data signal. After the predetermined time, the pulse-mask unit and the data output unit continue to output the rest of the clock signals and the print data signal.Type: GrantFiled: April 18, 2010Date of Patent: July 9, 2013Assignee: Aetas Technology IncorporatedInventors: Wei-Ming Shen, Wen-Lung Chang
