WordPress Temporary Window Print Primer Tutorial
A few different themes contribute to today’s tutorial about presenting a Print button, for a temporary timeframe for the current user only, for our WordPress Blog …
- document fidelity and the role of (hardcopy) PDF which we’ve discussed here before
- Print Screen snapshot ideas, we last talked about with Windows Screenshot AutoHotKey Automation Primer Tutorial
- temporary WordPress functionality specific to a user for a WordPress “session” … but note, our “session” is different to PHP’s $_SESSION[] scope, instead working with $_GET[] as the “session” mechanism … about which you can read more at WordPress Temporary User CSS Primer Tutorial as shown below
- limits of HTML iframe applicability, about which you can read more here, thanks … an “http[s]://” URL cannot iframe a “file://” URL, as much as we’d love to be able to do so today … it is a security risk to allow this … otherwise we’d have designed an instantly reactionary caller of Mac OS X (client computer) /usr/sbin/screencapture command to instantly snapshot the client screen … maybe you remember us not instantly using Mac OS X (client computer) /usr/sbin/screencapture command with crontab when we presented Mac OS X MAMP Timekeeping Web Application Email Tutorial recently

- works itself, as the concept you want to see … and …
