If the problem is due to the OS why does Office and every other application print OK?
Hi
Check also File▸Print▸Options tab▸Use only paper size from printer preferences (ticked or unticked)
Regards
Thanks but I have tried that. 
The Epson printer drivers are necessary for the operating system to interact with the printer. Without a printer driver, your Epson printer is not able to perform printing job. If the printer drivers installed on your computer are of wrong type, obsolete, incompatible or corrupt, the printer does not work correctly. Therefore to rectify or fix the issue, please inspect the printer drivers carefully.
What if Format–Page is greyed out???
You surely understand that this is not a common behaviour of LibO ‘Writer’ which is used successfully by millions of people (among them myself) for printing in either page orientation, also mixed from the same document. Thus the problem you have must be due to specifics of your OS / printer / printer driver / LibO installation / your documents (settings protections / …). Not knowing these specifics an answer might be impossible.
Did you already try to (e.g.)
- reset your user profile?
- take your file to another computer (with a printer) and test there?
- completely uninstall your printer and reinstall it?
- look for an improved driver for your printer?
- completely uninstall (by means of your OS) LibO and reinstall the current version from scratch?
- print some newly created ‘Writer’ documents without much content?
How nice for you Lupp. But the problem really is with your beloved LibreOffice. I downloaded an older version and the problem resolved itself.

Not in the mood for kidding.
There are many reports meanwhile seeing this problem very specifically related to LibO under some Mac OSX versions when using the outdated US paper sizes (Letter e.g.).
If you are on a different OS and use internationally standardised paper I don’t have further advice.
(Decades ago were many issues related to cases where some parts of a software didn’t know of updates creating mandatory indirections concerning attributes formerly set directly. A revival? )
For me this permanently-stuck-in-Landscape print-problem occurs on two physically different Apple computers, running two different MacOS versions (namely 10.11.6 (El Capitan) and 10.12.6 (Sierra)), running two different LibreOffice versions (namely 5.3.6 and a fresh-install of 5.4.2). After a lot of experimentation, I found a workaround, that is posted below.
@JohnSidles: The post you commented on here, wrongly created as an answer, addressed a different issue. Or did you ever find the sub-menu item ‘Format’ > ‘Page…’ disabled in relation to your issue?
(Your workaround may help nonetheless in this case.)
It is an issue with LibreOffice. Go to Format>Page and change the Format from Letter to A4
Go back to your print screen and all should be right in the world.
I don’t have enuf points to upvote (bogus), but wanted to thank you for your answer. It’s amazing that no matter how high-tech we get, it’s always printing that drags us back to stone knives and bearskins mode.
Thank you for your advise! Changing the page format from Letter to A4 solved my printing problem. Now I can print in portrait mode instead of landscape.
Add my thanks; I was seeing the problem on all documents. It would even do it saving as PDF. Selecting A4 format, clicking apply, then selecting back to “Letter” (so my printer wouldn’t choke) fixed the problem.
Same problem with LO 5.4.1. I downloaded Version 5.3.4.2 and it prints fine.
Problem continues with LO Version: 5.3.6.1. Switching to A4 worked.
Suppose you were on ‘Letter’ (8.5 inch width by 11.0 inch height; 215.9 by 279.4 mm).
A workaround I would suggest but cannot test myself is to omit the predefined setting for width and height and to replace them by slightly reduced values. Reduce each by a 1/100 of an “inch”, and the printing to vertical pages should work.
The far better variant is, of course, to shift to the internationally standardized A4 if you have a chance to pull it through.
