Quality or Ink saving mode
Sometimes ( especially with laser printers ) quality of watermarks is not really nice.
Or printer may produce wrong output, despite preview window shows correct results. It may be because of bug in printer driver or limited functionality implemented in driver.
In this case priPrinter may generate complete image in memory and send it to printer. In that case we can avoid almost all problems in driver and provide most accurate results.
1. In order to enable this feature let's click on printer configuration icon holding Shift key:
2. Options for your printer will be opened. Here you should select Print As Bitmap mode.
3. In result of this selection more options will appear. You may leave everything as is. Or may change them later. DPI here is the resolution of image in memory. Higher DPI, more memory it will take and slower it will be transferred to printer. In most cases 300 is right choice.
However please note that printer itself should operate at highest possible DPI. In that case printer will be able to output color gradients in the best possible way and will interpolate them more accurate. As an example see Options for HP Laser Jet printer.
4. Now, after clicking OK background of printer icon will be changed to color dots. It shows that your printer is in raster mode.
Please note that for network printers this mode may be little bit slow! For local printers speed is almost the same, sometimes it works faster, sometimes slower.
5. In addition to this mode you may enable ink or toner saving mode. Just drag slider in order to change saving level. This implemented as post process filter and possible only in Print as bitmap mode. Filter removes continuous dark areas but preserves edges. It works better with pages full of dark graphics.
