Don't wait 30 seconds, wait 30 minutes and see if it prints.
From other reports it is starting to look like there might be a Mac process that is hogging a resource that is needed to print and it is just very slow to respond. Just because it says "not responding" does not mean that it is not still processing slowly.
Once it prints the first time then it seems to print fast after that.
You can also try booting into the "safe" mode and then see if it will print, but again wait if it is spinning.
