Keystroke Script/blue boxes not showing upon print

Hi there,

I am including keystroke script so that typed fillable text is automatically underlined. This shows up when opened in Acrobat, but does not show up when opened up in a browser (Google Chrome and Edge). Is there any way I can make the underline code OR the blue boxes show up on print.

I'm concerned my users won't open the document in Adobe, only in Google/Edge. Thank you!
