# An Error in Printing Equations in Chrome

This afternoon, I found that when I preview the print layout of the posts in Chrome, some Mathjax block equations enclosed with weren’t displayed properly. I think it should be due to my settings in sass/custom/_print.scss because the contents in Mathjax’s official demo can be rendered properly in the print preview.1 Therefore, I deleted some obsolete lines of code in that SCSS file .2 Actually, since it takes time for loading MathJax, if I open the print preview before the block equations are ready, then I will see the source code of those equations.
