No option to print pre-made custom page size

[BKA]

So I've spent the last two hours trying to print this scroll I'm making for work with no luck, and no solutions online.

Here is what I have done:

Made the new template based on my document and set it as default in openoffice.
I have also gone into my printer settings and made a custom print size that matches the exact same measurements as the template I made.

However, when I go to print in office the option I made is not there. There isn't another program I can open this document in given the save options in office, otherwise I would save it as a pdf and try to print from another program.

What am I missing? I absolutely need to get this scroll printed for work on Tuesday.

Please, help!
