PDF to Printer Fix:
Print PDF as an image
Problems can occur when you print a PDF file. For example, a PDF file can contain damaged content such as images or fonts that Acrobat cannot process during printing. Printing a PDF file as an image bypasses that processing by sending the printer a simple image of the document instead. This process can cause images and fonts to look slightly rougher, especially at the edges. However, you can specify the resolution in dots per inch (dpi) to suit your needs.
Adobe Acrobat has a solution where you can simply select the PDF to print and then choose to print the PDF as an image.
