There is no way to revert back. When asking Shopify support, all they do is forward it to there team as a suggestion to switch back. They have no intent to help or actually do anything about this.
I have been using ShipStation thru my business Paypal account… and the rates are a lot cheaper than Shopify…in some cases it has been half as much. If the customer pays with Paypal, it is no extra work to print the label… if they use credit card, i just copy/paste the shipping address and its done. We pay Shopify for a service, and they won’t listen to us, so screw them.
Submitted a complaint~ This change also got rid of the dropdown feature showing all the items of orders on the print label page too.
Now, instead of staying on one page when fulfilling orders, I have to refer to the label page to find the orders I am fulfilling (i dont always fulfill in order of date), then go hand select orders to see the items. This was a huge L for community! It’s an unnecessary time suck! Please change it back Shopify!
Thanks for submitting this to Shopify. I like the old way so much better! I
hope Shopify changes it back. I like the old way of how everything was on
one page
I’ll just leave this here in case anyone is looking for a less cumbersome solution. I can see someone mentioned going back to a third party shipping platform - I’d recommend this approach if you want a bit more control over your printing.
All of these platforms handle label printing a bit differently, but with Starshipit (as an example), you can do trigger printing automatically when orders come into your account or scan to print with a barcode scanner. You can also just print from the same orders page too 
Just food for thought!
Just FYI, I tried to submit feedback to customer service, and all they responded was that they cannot go back to the previous way ?? 
. I’m assuming they didn’t even submit the feedback to upper management. The more and more I use this new label process, the more it’s frustrating. I noticed we cannot even search for a specific shipping box like before. I would need to click the drop-down button and scroll through the list of many different box/package sizes I use. I really don’t see how this new way of purchasing a shipping label was an improvement over the previous method. Waiting for Shopify to make an improvement on this improvement.
Hi ayellowgiraffe, I agree. I am having a harder time getting support as
well. I waited in the chat over an hour with no human response. The old way
of labels was much better as you were saying with all on one page and
choice of flat rate USPS and others. I might be using shipstation more now
with this change that Shopify has done but it was so much easier the old
way especially with return labels
I will keep you posted and I will try to connect with support again. I am
also disappointed they dont really have a vacation mode that allows you to
keep store open as normal with a note to customer before ordering of any
delay in shipping. I researched the net on this and the only solution
possibly is an app called ETA
Have a great day
Rob
Shopify actually listened. They have reverted back to the “old” single label workflow.
Thats great! Thanks for the update and have a nice weekend!
Regards, Rob
Yes! Thank you Shopify! 
I just noticed it too today and am SO. RELIEVED. 
We ship with Shippo but I have always printed packing lists from Shopify because they looked better and don’t have the prices on, so we can use them for gift shipments, too. We have been doing a large seminar for a few days and the orders coming in so far this week have been for customized items we will need to build, so I have not needed a packing slip for a few days. I didn’t find the new change till just now.
Today I tried to print a packing list and could not. first I could not find the command as they have created a new “print” pull down menu,it tried to get me to download the dang thing, which I do not need to do, we do not save copies of packing lists. Then when I clicked cancel it went to “generating packing slip” with a whirling arrow, it has been doing that for maybe 5 minutes now. So today I will have to create a packing slip in Word or use the Shippo one.
Plus, in the more actions pull down menu, they’ve moved things that used to be easily accessable and added an order status page, which makes you log into your store, rather than working from admin.
It is getting harder and harder to get anything done in Shopify. It keeps getting more complicated without adding any benefit to the vendor, but rather makes you need to buy an app, another leech feeding off your store, to do things shopify used to do.
If Shopify is going to do “improvements” whether we need or want them anyhow, then, Shopify, please at least make sure the “improvements” are funcitional before dumping them on us.
I still don’t have a packing slip, the page still has the busy arrow and “Generating packing slip” after 10 or so minutes
Hi there, @mom-n-pop . Thanks for taking the time to follow up on this thread, and provide us with this feedback around these changes. First, if you’re experiencing an infinite load with your packing slip, please attempt to print the slip again using a new window. I just tested the print functionality on my own store and did not encounter this infinite load issue, so it’s likely local to your device, so trying again should resolve things. Additionally, I was not prompted to ‘download’ a copy of my packing slip on my device when selecting the option to print one. Instead, my device loaded up a device-specific viewer that showed me the slip as a PDF, and allowed me to print from there, which is typical for my device. If you encounter additional oddities that you’re unable to resolve by using a different window, device, or refreshing the page, please reach out to our Team via our Help Center so we can get you authenticated and look into this via your store specific context.
I’m happy to go ahead and pass along the feedback you’ve shared here with our Team for their consideration. I can’t promise what may result from the sharing of your feedback with the team, but rest assured they’ll have the context you’ve provided here in mind when considering updates in the future.
The problem has not resolved itself. I tried to attach a snaggit of the save pop up but you don’t accept .jpg files. I have to get this order out now so I will use a Shippo label, which isn’t as nice.
If I try to print in a new page, it brings up the print page, but with the order, not the packing slip. If I do try to save it I get the unending “generating” arrow. I left the store, I rebooted, I made sure the adblocker ignored this site. I will try a different device but now I have to pack an order. Thanks for trying
Problem turned out to be an update to Chrome that changed all of our settings.
So Shopify was not in the wrong here, the new changes do function.
Thank you for your help
Thank you for following up with us and letting us know, @mom-n-pop !
