Publication number: 20040001216Abstract: A method that prevents a printer from repeatedly printing to a document is disclosed. The printer includes a sensor, and the printer is capable of receiving the document and printing data onto the document. When the printer prints to the document, the printer can also print a printing sign onto the document. The method includes, after the printer has received the document, using the sensor to detect whether the document has the printing sign. If the document does not have the printing sign, the printer starts to print data onto the document. If the document has the printing sign, the printer ejects the document without printing to it.Type: ApplicationFiled: September 5, 2002Publication date: January 1, 2004Inventors: Sheng-Chih Lin, Kuan-Chih Huang
