Pixma Pro-1 dimensions

My HP B9180 is starting to fall apart and even buying new ink tanks is throwing good money after bad. I have my eye on the Canon Pixma Pro-1 and have a question about the minimum size of support it needs to rest on. I appreciate from reviews what the actual dimensions are, but what I need to know is where the "feet" are, to see if my present printer trolley with a 390mm front - back dimension, will actually support the printer (albeit that the printer body will overhang a bit).
If anyone has this printer would they mind having a look for me?
Incidentally is the top of the printer "load bearing" - could I sit my Pixma iP4500 on top of it (as I do on top of the B9180)?

Kind regards
