I also occasionally get a jumble of characters instead of the document, spread over loads of extra / unwanted new pages with just a few lines printed per page - see pic. But I have not noticed a correlation to using Apple Preview or Adobe reader.
Not sure what causes theproblem for me, but I suspect some kind of timing issue or confusion inside the B210. I have mine connected via USB cable and via wifi (and have defined 2 different printers in my MacOS settings: one via wifi the other via USB). Perhaps that confuses it?
Also, I think it needs a good time (30 secs to a minute?) to switch on properly after being powered off or in standby, and I get the impression the 'random characters problem' is more likely if I launch the print command before the B210 has woken up properly. Perhaps your Preview and Acrobat reader have slightly different timing behaviour?
So I now make sure that the printer is fully ready (not in standby) before pressing "Print", and tend to avoid switching between wifi and USB connection (though they both work, usually).
If I do start getting random characters, I pull out the paper tray to stop the printing, switch off main power, clear the print queue on the computer, wait a few minutes to calm myself down, and start again, leaving the B210 plenty of time to get organised. Usually works, but is a pain in the neck.
To get it installed in the first place, I also used a Windows machine, plus the advice of a post elsewhere in this thread.
When it does wok, I am happy with the result. But sometimes I think I should have bitten the bullet and returned it to the retailer. Would have avoided more inconvenience and aggro in the long run.
