Folks, I installed Lexmark Mobile Print on my A2109. If you type in the IP address of the printer, it quickly recognizes the printer if it is on a wireless router. Under Adobe Acrobat, I hit "Share", chose "Lexmark Mobile Print", the laser spun up and started shooting out pages of crap, one or two lines of garbled PostScript, and there is NO way to turn it off from inside JB! Perhaps I have incorrectly set up the PS rendering. Possible. But the only way to stop the MS310dn was to hit the power switch. Hitting the "X" on the operator panel only paused the print job. I would classify Lexmark "Mobile Print" as not quite ready for prime time.
