Appends a blank page at the end of PDF file

[6vedant]

I noticed that for every PDF file created, I see a blank page unnecessarily added at the end of file. Can we remove it?

[brospars]

Could you share an example to reproduce ?

wearableOEM-rm-915-2k (2).pdf
index (2).pdf

check these two PDF files, i am getting a blank page appended as the last page.

This is a recent chrome bug :

• https://stackoverflow.com/questions/74698700/after-the-new-version-of-chrome108-it-adds-an-extra-blank-page-when-printing
• https://support.google.com/chrome/thread/191619088?hl=en&msgid=192661374

You can simply add the following to you extra.css :

body {
    contain: strict;
}

[drawlings]

I recommend contain: content instead of contain: strict, or else it will cut off everything but the first page, even if there is actual content there. This is what I put in extra.css to fix this issue:

@media print {
    body { contain: content; }
}
