i have just got a cannon ip4600 printer, now as most of you know a full face dvd has a printable surface of 48mm from hole to edge, but i cant print right up to the edge as the cannon software wont let me, i have e-mailed them and they were very unhelpfull and told me to use a 3rd party programe, i tried using my old epson software as that used to let me choose what i wanted the sizes to be, but it wont work, can someone help as all the dvd/games look gash with a big 5mm gap of white round the inner circle....

thanks in advance.....ivan...
