to enable recognizing identity of each page and sending the transformed print data to a printer the invention results in conservation of paper and toner while testing of printing systems and presents a uniform and general way of transforming print data by simplifying each page image the methods also include shifting printing position for each printing run to enable reuse of paper substitution with an identification number or scaled down image sending normal print data through optimized tester optimized tester generating print data using saved print file printer driver containing optimized tester embedding print data pdl with tester commands processing data through optimized tester parser and renderer within printer controller saving data in nvram and only storing log data corresponding to simplified transformed data into log storage without consumption of paper or toner application_number US 60761606 A description in the following detailed description numerous specific details are set forth in order to provide a thorough understanding of the present invention however it will be apparent to one of ordinary skill in the art that these specific details need not be used to practice the present invention in other instances well known structures interfaces and processes have not been shown in detail in order not to.
