A small native Mac app that takes the shipping labels you create on ups.com and prints them straight to your thermal label printer — correctly sized, first time, every time. No pop-up dance, no half-size PDFs, no UPS desktop software. £99 + VAT, once. No subscription. No per-label fees.
Built because we ship UPS parcels from a Mac every day.
The problem
If you've ever shipped UPS from a Mac, you already know:
You create the shipment, and the label… doesn't arrive. Blocked pop-ups get blamed. Browser settings get changed. The label still doesn't print.
When a label does appear, it's a PDF sized for an A4 laser printer — not your 4×6 thermal. So you crop, scale and hope, and the barcode comes out too small to scan.
Wasted labels, wasted time, a parcel queue building up behind one stuck label — every single shipping day. It's a five-second job that takes five minutes.
How it works
Drag the app into Applications and open it. It sits quietly in the background from then on — set it as a login item and forget it's there.
Use the UPS website exactly as you do now — same account, same shipment flow, nothing new to learn.
The label goes straight to your thermal printer at proper label size, rendered locally on your Mac. No pop-ups, no PDF resizing, no second attempts.
What you get
Not a browser extension, not UPS's desktop suite. A proper Mac app that does one thing and stays out of your way.
Built for ZPL thermal label printers — Zebra and compatible models — the printers ups.com fights hardest against on a Mac.
Labels are rendered locally on your Mac at true label size. Scannable barcodes, no cropping, no scaling guesswork.
Your labels and shipment data are processed on your own Mac. Nothing is sent to us — we never see a single address.
Print one label a week or two hundred a day — the price is the same: £99 + VAT, once.
One payment, perpetual licence for your business. It keeps working whether or not you ever speak to us again.
Pricing
Compare that with the time (and wasted labels) one bad shipping day costs you.
Not sure it fits your setup? Email ln3@sitelead.co.uk with your printer model and macOS version and we'll tell you straight — before you pay.
Just need one Mac fixed? Mac Bridge is the lean £30 + VAT version — same result, licensed to one Mac, a minimal background helper instead of the full app.
Requirements
Exactly what it does
Security considerations
Labels are rendered and printed locally — addresses and shipment details never leave your Mac. No sign-ups, no servers of ours involved.
The app does not phone home. What you print and when is your business, literally.
Every copy sold is individually watermarked to its buyer, which is how we can sell it once instead of renting it.
Guarantee & change policy
If the app stops doing what we said it does in your first three months, we fix it free.
Rarely — there are no marketplace APIs involved. macOS updates and printer drivers move slowly, and ups.com label output has been stable for years. If UPS does change something in your first three months, that is covered.
Fixes and new features are quoted at a fixed price — no subscription, no obligation, and the app keeps working regardless.
FAQ
No. That's the point. The app stands in for all of that — install it, and labels from ups.com print straight to your thermal printer.
ZPL thermal label printers — Zebra and the many compatible makes. If you're not sure what yours is, email us the model number before buying and we'll confirm.
You get a three-month guarantee: if the app stops doing what we said it does, we fix it free. After that — or for new features — we quote a fixed price for exactly the amendment you want. No subscription means no update treadmill, and the app keeps working regardless. Full policy on the before you buy page.
Labels are rendered and printed locally on your Mac. Your addresses and shipment details are never sent to us or anyone else.
The licence covers your business — install it on the Macs your business ships from. Each copy is watermarked to its buyer, so don't pass it around outside the business.
Email us your printer model and macOS version before you buy and we'll tell you honestly whether it fits. If something goes wrong after purchase, email us with your licence key — we built this for our own shipping desk and we'll get yours printing.
