What is the easiest way to print labels?

I have recently upgraded to 1.3.8h and now my FedEx automated shipping labels does not work.
I really like the mod but it appears that Numinix does not have a fix or new mod coming out anytime soon.
With that said, what would be the easiest way to print my FedEx labels since now I am manually copy and pasting them over to FedEx.com, creating a shipment for each order.

I am at 60 orders per day and this is causing a major backlog for me since I cannot type that fast and even if I could, I am swamped with other stuff.

What is everyone else using to print their FedEx labels and what is the closest method to what I am used to? I have shiprush for my Amazon orders but nothing for my Zen Cart orders?

Any help would be much appreciated and yes, I have to stay with FedEx due to my great discount and other perks.

Thanks in advance.

Doesn't shiprush incorporate fedex label printing?

Since Shiprush is the developer of the Stamps.com software for zencart, I would think they're quite capable of downloading zencart orders.
