How many volumn of solution do I need at least to smoothly process
print paper in a 12x16 tray? I am afraid my 2 liter bottle is not
enough to do this. Thanks.

Two liters should do even if it represents the diluted solution. If your
concern is the capacity of the solution, how many prints you can make with
it, then we need to know the developer in use. Fresh developer, of course.
Stop (if you use it) and fixers (2 baths) will work. It's best in a
situation with little solution to use a tray that has a flat bottom, or
minimal expressions. Take care not to let the paper get 'stuck' to the
bottom. (Stiction to be technical.)

Drifting a bit - I was lucky to have aquired several NIB 8"x10" curved
(commonly called 'canoe' shaped) stainless trays intended for processing
color paper. They are stainless in part to conduct heat, but they clean up
nicely too. They won't fit your paper unless you were speaking of
centimeters. They permit the use of very little chemistry. One 'rocks' the
tray on it's curved bottom. I use them for sheet film. One-shot chemistry.
