The 9890 is large printer and will be in the front room, and my main editing is done in a back room on a 52" display. I always do a small test print)s) before commiting toan expensiove pieces of 40 x 60" paper or canvas. Even with calibration or a profile thatr doesn't really represent say Exhibition Water5color pper, or Matte canvas.
I really don't want to hit print in one room and while LR is churning, run to the front room and see what's happening.
Seems reasonable to hae a small computer attached to the printer, and execute only the printing. Maybe do a 8x110, then examine, maybe needs more sharpening, or has too much, Then run the large print. That's where craftsmanship comes in, Not every image on every profiled paper or canvas is exactly the same. And my taste may be different when I print. Maybe I'd like it .25 brighter, or reduce the magenta .10. If that were true I could just upload to Costco to print.
So I'm guess it is noit possible to access the LR catalog on the "printer PC, and if needed adjust a slider or 2, and have those adjustments stored for future printing.
Thanks
