Fix print layout styling issues

Problem/Motivation

1. Vartheme provides printability-related classes in /scss/layout/print.layout.scss that has been replaced:
page-break-after -> break-after
page-break-before -> break-before
page-break-inside -> break-inside

2. The file is using invalid unit value to property width width:3;.

Proposed resolution

1. Replace the old css properties.
2. Remove the width line since I can't find a use for it.
