What is the error message?
Printer error, check printer...... I switched to another laptop and then printed from the printer software and it worked. I then tried to print from photoshop and it worked. I then tried to print it from my macbook pro & iMAC from Lightroom and still getting (printer error...check printer). It has to be lightroom.
This is the error report:E [16/Aug/2016:21:57:53 -0400] [Job 6] Unable to add document to print job.
