Slic3r 1.42.0-beta2 - Prusa Edition (win64)
Win 7 64bit
Prusa MK3S
Firmware: 3.7.0-2201
What happened to the Print Button?
Disable USB/serial connection
Under Configuration->Preferences, the following check mark item is no longer there:

Therefore, I can't connect to my printer and print directly like I could with the standard release of Slic3r PE 1.41.3+win64
Is there a different way to print directly to my printer?
This was a deliberate choice during the rewriting of the core components, from what I have read. It may be restored in the future but for now your only option is a third party tool like pronterface or octoprint to print directly from PC.
I need this print button. I like to USB USB printing for small print.
Kind of messed up to take away a useful feature and force people to be limited to one specific way of printing. I understand there are other programs that allow you to print via USB but if you want people to use your software above all others.....don't limit what they can do.
I believe this is a duplicate of #2046, closing in favor of that...
