M1536DNF Duplex garbled mess, Lion, Snow Leopard and Win 7

[fr1n63]

I've had my M1536DNF for about a year now, everything has been fine, great printer, no issues whatsoever until recently.

I attempted to print some flight information, set it for 2 sided and thought nothing of it, went over to collect print job, the sides facing me are fine, the back side was almost entirely horizontal lines, some text did print top and bottom though. Exactly the same result on second attempt. As I was going away, I didn't have time to mess with it so I printed single sided and promptly forgot about it. This was with a Mac OSX Lion.

Month or so later, my partner was trying to print a document from her Win 7 laptop, same issues, multiple attempts and nothing useful on the back side. Transferred the files to another Mac - Snow Leopard and still same issues.

I've re-booted the printer, cleaned the printer, downloaded new drivers (which are not available for Lion yet so I don't know how this thing is working at all). Nothing seems to get it up and running again properly. Has something died on my printer or is this a software issue. I'm guessing hardware as the issue is 100% reproduceable from multiple machines, multiple operating systems.

At no point have I seen an error from the printer or print utility.

As an additional note, I've just tried swapping the toner, didn't want to try that as I had 70% of a £55 unit in there. No difference.

Scratch all of that. The issue is Chrome - the beta print panel seems to destroy the duplex side.

Turn it off with these instructions.
