Abstract
A method of processing linearized and non-linearized Portable Document Format (PDF) files for printing comprises: determining by printer firmware if a printer driver detected that the PDF file is linearized; saving stream data of the PDF file by the printer firmware when the printer firmware determines the printer driver detected that the PDF file is linearized; and determining by the printer firmware if the PDF file is linearized when the PDF file is unidentified as being linearized by the printer driver, wherein the printer firmware identifies real and false linearization error during linearized processing and identifies and processes printing errors in a parallel manner during saving and interpreting stream data.
