The issue could be anything from missing (misbehaving print) software, to the PDF file content not being recognized by the printer, to the PDF / download having been protected against printing by the original author.
You may have to dig at this or the answer might be "right there".
If the file will not print due to unusual content (odd fonts, color schemes, tables, other oddities), print the file as an Image. Image printing does not require the printer software to translate file content.
