I have a Pixma iX6500 which has never given me any problems until now. I want to print a long chart 297 x 840mm which is A3 width A1 length. I am printing from Photoshop 14.0. I have set up the paper size for the printer as 297 x 840 and set the chart size in Photoshop to the same dimension but when I print it only prints the centre part of the chart and leaves a 45mm margin on either side of the paper. Can anyone help me overcome my problems?
