I’ve tried on my laptop, I’ve tried on my phone. It’s not working at all. I have all of the items that is needed, I wonder why it won’t connect to the Bluetooth either. I’ve tried multiple ways to connect it just isn’t.

This took some doing so I’m going to record how I did this here in hopes it will help someone else.0) get the printer plugged in and labels loaded.1) Know the dimensions of your labels in millimeters. 4x6 inch labels are 100x150mm for example.2) Open this app. Tap the printer icon in the top right and then tap Bluetooth printer. It should connect3) Go to the app that has the pdf you want to print, and open that PDF. I got this to work with a PDF I downloaded from Safari, but haven’t tried anything else.4) hit the share button - little box with an arrow coming out 5) scroll through the apps you could share with until you get to “more…” and tap it6) scroll down until you find this app - “print label”. Tap it.7) it will switch over to this app and it won’t look like anything happened. Get back to the home page if you aren’t there already and tap the pus sign button at the bottom8) we’re almost done I swear9) tap the PDF button and you should get a list that includes the PDF you shared.10) you should now see your pdf. Make sure the width and height in mm are set correctly for your labels.11) hit Print!Just that easy.

I don’t know why this app gets a lot of negativity. I bought a Bluetooth thermal printer from eBay for about $105. I use this app to print my PDF file shipping labels from my iPhone XR and it works every time for me. The labels look clear and this app always downloads them on my first try. So I have to give the app 5 stars and hope everyone else has better luck next time and just spend some time going thru the app and play with all the settings. Took me about 20 mins till I figured out the app on how to print my labels.

Install the app, then select the printer at the top right corner, select Bluetooth, tap where is says none to connect.Go to the PDF and. ( don’t select print because it will say no AirPrinter found) scroll until you see the Icon of this app and select it. It will re direct you to the App and tap the (+) button and select pdf! It should show your pdf! Hit print and make sure you have paper (100 mm x 150 mm)
