Single suggestion addressed by KenK:
- Which Print dialog appears?

I just use Gmail's Print command.

That initiates a call to Firefox to use Firefox's Print function which
in turn initiates the OS standard Print dialog (Firefox defers the Print
function to the OS instead of providing their own). Gmail cannot do any
printing (unless it goes to Google Cloud Print service). It has to rely
on the Print function in the web client connecting to their site.

So, for the Print dialog that you see, do you see the standard OS Print
dialog, the same one you see in other programs when you print from them?
Does the Print dialog you see look similar to:

https://docs.microsoft.com/en-us/win...ialogboxxp.png

Or does it look like a print dialog presented by the ancilliary software
installed for whatever printer you installed, or somehow look very
different than the standard Print dialog presented by the OS?

If you're not sure how to describe any differences you see in the Print
dialog, grab a snapshot, upload to online storage (e.g., Imgur, TinyPic)
and give a URL here, so others can see what you see.
