I’ve got 4 printers running on astroboxes at the moment with a plan for 2 more. It would be great if I could click on a print file for a model and then select all printers or say send to all printers. Its not a huge hassle now to click print on the first then close the pop up, then open the dialogue and select print for hte next one, but it is a little tedious!
Interesting suggestion.
While this is a very specific and isolated use case, I certainly understand the need for it…
This, along with automatic bed clearing would essentially bring you a fully automated mini factory 
A variation of this is possible when we release queueing. That is you can place an object in a queue multiple time and have different printers that are idle pick one up. I think that would essentially satisfy your requirement in a slightly different way. correct?
Thanks for your suggestion
