I use Lightroom Classic and an iMac to print with my Pro-1000. The PRINT module of Lr has a "Print Resolution" checkbox. When checked, you can chose the number of PPI.
For optimal output on a variety of photo papers:
1. Should the box be checked?
2. If so, what number of PPI should be used?
3. Does it change with the size of the print?
Many thanks in advance,
R
