Check out Java Print Service API The javax.print.attribute and javax.print.attribute.standard packages define print attributes which describe the capabilities of a print service, specify the requirements of a print job, and track the progress of the print job.

For example, if you would like to use A4 paper format and print three copies of your document you will have to create a set of the following attributes implementing the PrintRequestAttributeSet interface:

PrintRequestAttributeSet attr_set = new HashPrintRequestAttributeSet();
attr_set.add(MediaSizeName.ISO_A4); 
attr_set.add(new Copies(3)); 

Then you must pass the attribute set to the print job's print method, along with the DocFlavor.

MediaSize.ISO.A4 or MediaSize.ISO_A4 doesn't work. Instead MediaSizeName.ISO_A4 is correct.
