Hello dawid.ostafin,

According to our documentation: PDFTron

The recommended values are 2 to 5. 2 or 3 is suitable for most purposes. Values higher than 5 will have diminishing returns in terms of increasing quality. Note that it has no effect on the printed document quality if using embedded printing.

This means embedded printing quality is not determined by our API. printInBackground uses the embedded printing option.

So is there any option to improve quality of embedded printing or do I have to use print() to get high quality PDF?
