Printout of "The Rust Programming Language" is truncated

[jimis]

Using Firefox, go to "The Rust Programming Language" manual page and click on the print button on the upper right corner. The print dialog pops-up, so select "print to PDF". The full URL is this:

https://doc.rust-lang.org/book/2018-edition/print.html

Results: The margins are messed up. The left half of the page is empty, the right half is missing (text is truncated in all pages). See attachment "mozilla.pdf", which is a printout of the first 10 pages of the manual.
