Inserting a PDF or other image into drawing

We have circumstances at times where we have a dgn that we would like to insert a picture from a PDF file.

We have tried several different ways to do this without achieving the desired result.

We have tried saving the PDF as a .jpg file and using File>Import>Image. This gives us a pretty clear image on the screen but when we print it is not even close to readable.

We have also tried leaving it as a PDF file and using Edit>Insert Object. This gives us a more blurry shot on screen and is also not even close to being legible when we print.

It doesnt seem to be our printer because we have tried the same thing with AutoCad and got a better result. Just wondering if there is a trick we are missing. We would like it legible on screen and when you print.

 Thanks for the help!!
