Retail Barcode Labels

I am using this app to create and print labels for products we sell in our shop. It was working fine so far and was really easy and with just few steps I was able to print barcodes. We use Demo LabelWriter 450. I didn't need to use the app for a few weeks but yesterday I had to print few barcodes and it is not working fine anymore.
It prints only parts of the information on the label. I've been trying different settings, followed the instructions and recommendations from the app help page, noting seems to work.
Could you please give me any idea how to deal with this case?

Thank you

This app is free and yet somehow still I'm disappointed. It is restricted to a limited range of labels from 3 specific brands of labels with specific brands/models of printers. (conveniently printers you can buy from the Shopify store.) You'd think this thing would be highly optimized for said printers, but I've had so many issues. For example, just today I had the labels just randomly start printing sideways. Like, between print-jobs using the same template, minutes apart. Shopify has a bad habit of creating apps and then never supporting or improving them, and sadly this is one of them.

Update: 01/11/2023.
No noticeable updates, but through some tinkering, I've been able to get it to work and it does print labels, so I'm upgrading it from 1 to 2 stars. However, another noticeable issue is the clunkiness in regards to bulk controls. You can't, for example, filter your search to a product category and select all, and you can't copy past a quantity down a row like you can if you were bulk editing something in Shopify. This is being mentioned because I recently needed to print one of each label, for the purpose of sticking on bins (a pretty fair use-case) and that involved me individually searching each item and then individually setting the quantity to 1. Very very very tedious, and if you have a warehouse full of SKU's, you're in for a bad time.

I appreciate Imogen's response, and I genuinely hope to see this app improve, but it really does feel like it's being neglected.

I was pretty nervous to install this as there are SO many bad reviews. BUT, they must have fixed some bugs because I just installed it and was using it in less than 2 minutes. It worked with my old barcodes and I found it easier to avoid mistakes than the old app. It opens a pop up on my browser when you send it to the printer. Maybe some people have a complete pop up block so that stops it from printing? Who knows, but go ahead and install this one, your store isn't going to implode.

Worst app ever! I had to chat with shopify for 3 hours to try to get it to work and it still does not work. I think it is horrific that they are getting rid of the the old barcode printer app while this one does not work for many They should at least keep the other one active for those that this is not working for. This is a BIG problem for those of us that cannot print barcodes using this new app. Please tell me this will be fixed before the cut off date. This is horrific.

I used this app to start using barcodes for the very first time and it was seamless. Very easy to use and a great time saver for stock control. Thanks

The app started randomly generating barcodes without our request, causing several issues with our integrations

love the app, super easy to set up and use, within 10 minuts I was up are ready to print, highly recommended.

No email back from support, barcodes are invalid. It would be a great app if the barcodes worked for google shop.

Hi! I love these barcodes but needs help making multiple item barcodes per sheet. Can you help me with that? Thank you!

I needed a while to figure out how it works. Lately we don't have any problems. Except it needs a long time to create the barcodes.
Of course, we would be happy, if this app would make it possible to create barcodes and print them directly from the inventary, right when products come in.
