Taken from the accepted answer here: Removing input placeholder on a printable version of an html page
You can use a print media query to change the text color transparent. It doesn't "remove" the text, but makes it invisible, so same result...
@media print {
::-webkit-input-placeholder { /* WebKit browsers */
color: transparent;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
color: transparent;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
color: transparent;
}
:-ms-input-placeholder { /* Internet Explorer 10+ */
color: transparent;
}
}
