Macbook pro, Photoshop CC, Canon ipf8400
I was seriously getting ready to return my new ipf8400. One month of frustration, wasted canvas, tech calls including 2 where the Canon techs remotely took over my mac, and much more!%&%$@. Was really beginning to hate this printer.
After landing on this forum and inserting the code as Doyle suggests, success! Thank you, thank you. I decided to join Luminous Landscape on the spot. So should the frigg'n Canon people.
For others that may land here too, the Canon print plug-in does not work at this time (at least on my Macbook pro) with Photoshop CC past the 2015.0 version. I tried repeatedly to get it to run while using 2015.1.x and it crashed all the time. Canon tech was stumped, so I updated to Photoshop 2015.5 thinking it might fix it. Even worse! Further, printing without the plug-in to the Canon 8400 was crap. Colors very wonky and over saturated.
Terrible work flow but I now use PS2015.5 for all my editing as I like the features, then have to close it and open 2015.0 to use my Canon printer. Without the fix as stated above, the printer will not/ can not produce properly profiled prints but at least looks great now.
This issue has been around for years so I have to wonder why the heck hasn't Canon updated that one file by now.
