I opted to upgrade Ubuntu to 14.04 and after not getting anywhere I downloaded and installed the latest hplip (3.15.11). This version of hplip now prints the document almost completely via USB connection. It is as if a buffer flush will print the remaining ~ 5mm (which basically consists of the drawing border). Also, paper is not ejected. (using the cdnj500 driver)
