Canon TM 200 not printing whole document

[printer_woes]

Hello,

I've got a new Canon TM 200 plotter. I'm trying to print a document that's 594 x 2184mm. My plotter keeps printing the document out portrait rather than landscape. It'll print about 60cm of plain paper then begin to print the document the wrong way around - when it gets to the edge of the paper stop printing. So I end up with a print out the wrong way around and only about 1/3 of print out on it!

I've changed the paper sizes to the correct size before printing but it still keeps doing it

Thanks in advance,
