Tilman Hausherr commented on PDFBOX-5633:
-----------------------------------------

This is a difficult decision. You have to weigh different factors:
- dpi 0 best quality but sometimes very slow (transparencies)
- dpi 1200 usually the dpi of your printer, but rendering at 1200dpi will also 
use lots of RAM, and will be slow if you have large shadings (gradients)
- dpi 300 is a acceptable quality for the untrained eye
- dpi 600 is a good compromise

> We use PDFBox from our java application to send documents to print to a 
> physical printer. 
> But we see a significant increase in size of the pdf document when printed on 
> a konica minolta printer around 40x time in spool size. Thus, resulting in 
> higher time taken to print.
>  
> we have set the DPI to 0 which results in some imporvement but still we see a 
> 40x time increase in size
