Printer resolution (limits), "native resolution", quality enhancement settings

Hi,

I’m trying to wrap my head around all the stuff concerning resolution of my Epson P800, or printers in general, hopefully being able to provide some corrections for my printer, as it’s still „EXPERIMENTAL“.

For now, I’m trying to understand:
1) How are the different printing resolutions chosen? Why is there no „5760x5760“ setting, or even higher?
2) What’s the limit for printer resolution given, a specific printer? My P800 is listed with a maximum resolution of 2880x1440, how does Gutenprint achieve a higher resolution than this?
3) I’ve read some stuff about „native printer resolution“ - as I understand it, that’s the resolution the driver down-/upsamples every raster graphic send to it. How is this chosen for a specific printer in Gutenprint, and why? Do the choice of printing resolution does have any impact on this?
4) What does the „Quality Enhancement“ setting do, and how is it concerned by printer resolution?

Thank you so much in advance for you explanations! :D
