Hi hlessig,
I am having the same problem as well and I'm on Mac OS X 10.8.3 on a 13" MBP Retina.
However, I can print to a SHARP MX-3100N printer just fine with the MacOSX10.8.x PS PPD 10.8x Driver for MX-3100N driver that I downloaded from the sharpusa.com website.
I downloaded and installed the MacOSX10.8.x PS PPD 10.8x Driver for MX-2700N driver and I am able to add the printer fine in System Preferences/Print & Scan. I added the printer as an IP printer using the HP Jetdirect - Socket like I did for the MX-3100N. Jobs appear to print to the printer just fine. However, the printout I get is:
%! PS-Adobe-3.0 Query
userdict(\004)cvn{(\004) print flush}put
%%BeginFeatureQuery
I tried deleting and adding the printer using the IPP and LPD protocols with no change.
I was able to print black and white to the MX-2700N by downloading and installing the latest Gutenprint driver set and choosing the SHARP AR161 printer. However, I couldn't print color which is what I really need.
I thought perhaps that the PS3 expansion kit needed to be installed on the MX-2700N. However, the MX-3100N does not havfe the PS3 expansion kit installed and I can print B&W and color to it just fine.
It appears to be a SHARP driver issue. My printer service company has a ticket opened with SHARP. So, we'll see what happens.
