Printer is distorting or re-orienting images

I have a Canon Pro 9000 Mark 11. It has suddenly started to squash images into a small area or to print them smaller and sideways. i.e. A portrait image can be squashed into the bottom of the page (Lightroom) or it is turned through 90 degrees and printed in proportion but half size across the top of the page (Photoshop). I am unable to change the dimensions in Lightroom - in the 'Print' dialogue box the 'cells' toward the bottom of the page remain 'fixed'. Anyone any ideas? I have just updated the driver for the printer but it is still the same.

it sounds like you have the scale setting on the canon print dialogue set to something other than 100% and / or the same for the lightroom print dialogue.
Lightroom is telling the printer to do one thing whereas the driver forces it another way
go into the print settings and check what you have, making sure the paper is the correct size, orientation and scale..
other than that, does it do the same from any other package / word, chrome etc?

Thanks guys for all those thoughts. I have recently updated Windows and it has very kindly 'lost' all my personal files - letters, and addresses. So I actually don't have anything else to print.
It seems as though it may have something to do with the Adobe software being able to 'talk' to my printer - somewhere. I have checked all the print dialogues and they refuse to be changed. I turned everything off and then on again and it worked for one print but then it gets stuck in one format and that can't be changed.

Thank you again everyone - took all of your advice on board and at least Lightroom is working properly now. I rarely use Photoshop for printing but tried it and that still seems to be misbehaving. I will delete it and reinstall, hoping that then it will resolve its' issues. Very grateful for such superb thoughts - happy Christmas to you all.
