"I got satisfaction using this to run my POS business. A customer discouraged by my traditional machine ended up fully satisfied once she saw the printout — that's the beauty of this app."
"Works very well and can be used by professionals and amateurs alike. Customer support answers queries in a timely, professional manner. You can save templates and import/export data to save time."
"I've previously tried other apps and they all came with loads of headaches. I'm glad this one works perfectly for me. Great job, team."
"Exactly what I wanted. I got a $20 Bluetooth receipt printer and some thermal sticker labels, and now I have a tiny label maker I can use with my phone anywhere I go. Absolute game changer."
"Been searching endlessly for an easy-to-use app to print receipts — the others take too long or are too complicated. The short-codes even let me print an automatic date and time on every receipt."
"My printer didn't come with an app, but this helped me print almost anything — images, barcodes, QR codes, a full template. Genuinely useful."
