Landscape document will only print in portrait
I have prepared an A4 document in landscape format, but whenever I try to print it (including converting to pdf), the print preview changes to portrait format. This applies to both of my two printers (Canon MG7150 and HP LaserJet 1022). In previous years at this time - ie, with earlier versions of Mac OS and Pages - I have been able to print in landscape without difficulty. In the printer menus, the 'Layout direction' buttons are greyed out. Help welcome!
iMac, Mac OS X (10.6.8)
