of course thank you,
I went to the custom paper dimension making tool, and in the "custom length" column my question is answered:
3582.68 inches = 298ft+/-
Now how I got the idea that the driver won't successfully print out panoramas bigger than 90.3", or 103",or other guesses?!?,
is beyond me at the moment, so I'll be happy for the opportunity to reason this through,
thank you
