PDFs do not print - ImageCLASS MF445dw

[JinRoh]

I have a Mac Book Pro.  Word and Excel files print fine but PDFs either dont print or take forever.  I updated the firmware.  Ive also tried using both preview and adobe.

Update on this.  PDFs print as long as they are a small file like 50k but if its 500k it will take 10-20 minutes to print one page.  Is there a way fix this?

Further update....sorry, its not letting me edit posts.  Anyway, I can print a 2.1mb word file no problem.

This is actually going to be difficult to troubleshoot.  A PDF is a complex format that can simply hold a bitmap (rasterized image) to having tens-of-thousands (or more) separate drawing instructions.  Thus, the size of the PDF won't be enough to know why it's taking a long time.

What software created the PDF?  How many pages is it?
