When sending prints from the print queue, you can see the current transfer status in the bottom left of the page. The first printer you sent to is at the top and the bottom is at the bottom of the grouping.
When sending multiple prints at the same time, it’s more helpful to see the last printer to sent files to rather than the first. In it’s current iteration you have to scroll down in the box to find the last sent machine so you know where to start sending the next batch of files.
Suggestion is to just reverse the order so the last machine that received the file is at the top rather than at the bottom.
