[JAVA2D] Printing Resolution
How do I take advantage of the full resolution of the printer? When I do a default print using the printer service I seem to get the resolution of the window that I am printing, is there some way of getting the resolution of the printer not that of the display device? I have a Java2D graphics window, and have tried the following with no success: Graphics2D graphics2D = (Graphics2D) graphics; // Scale the printout to fit the pages. double scalex = format.getImageableWidth() / getWidth(); double scaley = format.getImageableHeight() / getHeight(); double scale = Math.min(scalex, scaley); // translate to the printable (0,0) location on the paper. graphics2D.translate((int) format.getImageableX(), (int) format.getImageableY()); graphics2D.scale(scale, scale); // then paint the graphics 2D object. I still get jagged lines on the printer device. The original window maybe displayed at 600x600.

Re: [JAVA2D] Printing Resolution
I suspect you are printing a double-buffered swing component window using paint(). That paints to the swing back buffer which is unsurprisingly at screen resolution and then that is what you are sending to the printer. Use Component.printAll() to print a Component, *not* Component.paint(). -phil. [EMAIL PROTECTED] wrote: How do I take advantage of the full resolution of the printer?

[JAVA2D] Printing resolution
All this talk of PageAttributes and printing has reminded me of a strange problem I have here. I'm using JDK1.3 under Windows 98 and printing to an Epson Stylus printer. If I print a load of vector stuff, lines circles etc. then everything gets printed at printer resolution and is fine. If, however I print a background image, the resolution of all the vectors goes down to what likes like about 100 dpi, but may be 72dpi. How can I avoid this?
