WASTE OF MONEY. The app is horrible. the printer is horrible. I'm about to smash the thing to pieces. no matter what settings I put in the label is offset. smart cropping? WHAT A JOKE! Now I have to cough up more money to get a new printer that doesn't slow me down so much that I don't even want to work anymore. You owe me $18 for the labels I've wasted and about $40 for the printer and frustration you've caused me.

I'm liking it for basic functions so far. I haven't used all the options, but all I need is to be able to crop the shipping label and print it. The only thing I wish would be better is that after you crop it you can click it a button to make it fit the whole page size you first selected. Right now you have to manually adjust it.

It worked well before the latest update (6/12/24), it took out the "receipt" option and the 3 "print mode" options all make anything new i make print in gibberish. The tutorial says to put in bill mode for continuous print, but that's not even an option anymore. I also wish it wasn't so jumpy when editing the text but i kindy got used to it.
