I cant print landscape from pages on my Imac.

Hello cellas1,

I understand you are not able to print a document from Pages in landscape orientation on your Mac. Is this issue isolated to a single document or have you tried a different file? If you are unable to print ANY document in landscape mode on your Mac, you may need to reset the printing system.

Hello cellas 1,

Thanks for your response. What version of Pages are you working with, and what model printer? Are you able to print in landscape mode in other applications? We still need to determine if this is a Pages issue or a printer issue. Resetting the printer is a good troubleshooting step. I've included a few more links below with printer information. Is your model on the list of compatible printers? If so, the software included in Yosemite is all you need. If the model is not listed, follow the link in the document to the printer manufacturer's website for more information. If your profile is correct, it looks like you may need to update Yosemite to the latest version as well.
