2 Can anyone suggest more feasible settings for good printing quality?
I usually have a canvas size of 24x28inches at a resolution of 350ppi using photoshop, Krita or painter, but the best I can do with PSS is 6000x7000p with the ppi only 72 (100 is workable but irritating to use after a while with larger brushes and blending, due to lag on moderately fast stokes and, above.)
If you use pixels - the DPI doe's not mattered. DPI is just comfortable thing to store your print size, but increase quality. For example - you know that your print size is 10'x10' inches but it's only 720x720 px, and you increase pdi to 300 to get 3000x3000px but if you already increase your canvas size in pixels dimension - dpi will not give any effect.
Maximum quality of 99% printers is 300DPI. Also, Sometime polygraphic company show their services like 1200DPI or something same - it's a wrong understanding of DPI meaning.
What about performance, the current version works fast only at brushes near 200px size. You should wait a little for a new release, it supports large canvases and some types of brushes "fly" with 1000px size. (If you drawing by hairy brushes - it will slow at every soft with large size. )
