Digital BW, The Print

I want to purchase a printer (1160) from a source in Europe but I 
have 2 questions:

Question 1:
The paper sizes are different (letter & legal etc., as opposed to A3 
& A4 etc)- would it work to download and use a "local" driver and use 
north american paper sizes.
Is there any mechanical aspect to the above question that's 
different ?

Question 2: Europe is on 220Volt main power supply and we are on 110-
120Volt - are the printer voltages switchable ?

thank you
Frank
