Description:
New documents print and export to pdf with content shrunken on page. Existing documents created under older versions of LibreOffice print and export ok. Changing those older documents' content in new version and saving does not manifest the issue either. 
Resetting user profile does not fix
Changing fonts does not fix

Steps to Reproduce:
1. Create a new document
2. Select print or export to pdf
3. Result is content shrunk by about 60%

Actual Results:
Printing and pdf creation reduces content of results to about 60%

Expected Results:
Printing and pdf retains 100% scaling


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Existing documents created under older versions of Libreoffice like 4 or 5.0 can be printed and exported without shrinkage
