Defining print orientation

Hi, I'm having an issue with printing a webpage direct from the browser built using bootstrap studio. The page prints the content I want (using the responsive display print options) but a third of the page is missing/overhanging on A4 portrait. If I set my printer to landscape it prints everything exactly as I would expect it to. Is there a way to set it to print in portrait mode containing all the pages content?

I've just noticed that it prints as expected in chrome, and also in firefox if I check the 'shrink to fit page width' box (but I presume that this box isn't check as default). So is there a way to set the 'shrink to fit page width' within bootstrap studio?

Thanks in advance
