Make the " Start print after transfer" checkbox easier to click

[floretan]

I've been enjoying the web interface a lot, and I appreciate all the attention to detail that went into it. One minor thing that I noticed in my workflow is that clicking the "Start print after transfer" checkbox always takes a bit more focus and effort, when everything else in the user interface is nice, big and easy to click.

The label of the checkbox is already clickable, which is good, but the bounding box is just the text itself with no padding. My proposal would be:

• Move the checkbox element inside of the label (the for attribute is then not needed) this way we have a continuous clickable surface.
• Add some padding to increase the clickable surface. This doesn't change the layout.
• Optionally make the checkbox and the text bigger. It's currently small due to being in a div with a "txt-sm" class.

Since there is a confirmation modal after clicking, the risk of increasing accidental clicks should not be an issue.
