Set the print properties to construct a new empty print request property set. Printrequestattributeset Pras = new Hashprintrequestattributeset ();p Ras.add (New Copies (3));//print copies, 3 copies// Sets the format of the printed data docflavor.byte_array. PNG MIME type = "Image/png", prints the data representation of the class name = "[B" (byte array) of the Docflavor. Docflavor flavor = Docflavor.byte_array. png;//Find all eligible Print Services Lookupprintservices (flavor, Pras); Find the docflavor that can print the specified printservice. printservice[] Printservice = printservicelookup.lookupprintservices (flavor, Pras);//Match all the found printers to the printer you want,    Find the printer you want Lookupprint p=new lookupprint ();    Printservice Myprintservice = P.getprintservice ("Printname"); The PrinterJob class is the main class that controls printing.    The application calls the methods in this class to set the job, optionally calls the Print dialog box with the user, and then prints the page of the job.                                                 Getprinterjob () Creates and returns the PrinterJob associated with the default printer when it is initialized.  Print task PrinterJob job = Printerjob.getprinterjob ();//setprintservice (Printservice service) This printerjob with the new Printservice                         Association.    Hang the task on the Service Job.setprintservice (Myprintservice); PDDocument This is an in-memory representation of the PDF document. When the document is no longer needed, you must call #close (Method Load (file file) parses a PDF.    The unrestricted main memory will be used to buffer the PDF stream. PDDocument document = Pddocument.load (new File ("Printpath"));//convert PDF document to PDF stream into memory//paper class describes the physical characteristics of a sheet of paper.
