Q: Does jPDFPrint convert the PDF document to images before printing or does it send the PDF document to the printer directly as a PDF?
A: None of the above. jPDFPrint does NOT convert to images and does NOT send the PDF directly: jPDFPrint reads and interprets the PDF document and then sends drawing commands to the printer. The drawing commands are lower level commands, such as draw line, draw a string with a given font, draw an image, etc. The commands are actually sent to the printer driver, which then converts to the printer’s command language and sends them to the physical printer.
