Hello,
Here are our observations:
- The Google Chrome internal PDF viewer displays the PDF correctly. The issue happens only in the Print dialog when the "Fit to page" option is enabled.
- Firefox now uses pdf.js which is currently in an experimental phase and is not rendering the PDF file correctly.
- Other PDF rendering software displays the PDF correctly.
Just for your information, this is not matter of the past few days. We received another support request from you two months age (on Feb 7th) with a PDF file attached and that PDF file exhibits the same problem.
Our conclusion is that this may be a regression in the Chrome Print module, see for example here:
