When testing with HP Designjet large format plotters we found that:
- If you select Optimize for Images and Maximum Quality, the plotter reduces the output resolution to 600 dpi.
- If you select Optimize for Drawings/Text and Maximum Quality, you can increase the output resolution to 1200 dpi.
For example: By setting a paper size of 50 x 50 inches and using the Optimize for Images option with the Maximum Quality setting, you can successfully output an image of 30,000 pixels.
