Finally got a chance to do a few test prints with the Pixma Pro-1. I printed on Museo Silver Rag, from both Lightroom (see CONS) and Photoshop. These are my quick impressions.
-Extremely quiet - barely notice it's printing and don't consciously hear it finish
-Print quality is extremely high - much better than my 9500 II
-Relatively quick printing on my highest quality setting
-B&W images are beautiful and rich when printed as grayscale (see CONS)
-Color is vibrant, but accurate
-You MUST use the grayscale option to print B&W, otherwise the prints have a warm/yellow cast. This is VERY different from my iPF6100, where it -doesn't matter whether I send a print as grayscale or color to print a B&W image.
-Driver feels a little primative when setting up, but that might be just me.
-Printing from Lightroom yielded an incorrectly printed Last Inch. The image was approximately 10 inches with a .5" margin at each end, printed on Letter size paper. I had the same weird offset (last inch or so elevated above the rest of the image). This occurred with three prints from two images of the same subject (one color, one B&W). Photoshop did not produce the same printing error.
Overall, I'm much more impressed than i was with the 9500 II. To be honest, I always hated that printer and regretted my purchase. It was my first desktop printer purchase in nearly 8-years. (I used my Epson 4000 for years, eventually replaced by my iPF6100.) I'm just disturbed by the Lightroom printing results (is it a Lightroom bug??). I'm a little more disturbed that it does NOT produce a neutral B&W print, if you use all the inks, As I stated, my iPF6100 is the most neutral printer I've used to produce B&W prints (regardless if i send the images as color or grayscale), since my years with Piezography inks.
