Two things: No, and this is the wrong section. This should be in Ask a Pro.

it is possible if you store everything that is being printed in a table. Then you can look into that table what is being written where. It can be done for each character on every coordinate, or for each line. Just be creative with it, if you cant get it to work, there are some API's out there that make this possible for you

screen = {}
w, h = term.getSize()
for i = 1, w do
screen[i] = {}
end
oldWrite = term.write
function term.write(s)
s = string.gmatch(s, ".")
local x, y = term.getCursorPos()
for i = 0, #s-1 do
screen[x+i][y] = s[i+1]
end
end
function print(s)
term.write(s)
x, y = term.getCursorPos()
term.setCursorPos(1, y+1)
end
That should record the whole screen to a table, to see the character at x,y do screen[x][y]
