Quick Reference & Frequently Asked Questions
How does Thermallabelstudio convert 8.5x11 carrier sheets into 4x6 thermal labels?
It maps 8.5x11 (612x792pt) 1-up, 2-up, and FBA box label regions into exact 4x6 inch (288x432pt) portrait coordinates with 90-degree auto-rotation for Rollo and Zebra printers.
Why are UPS, FedEx, and USPS charging me extra postage adjustments after shipping?
Carriers bill whichever is greater: actual scale weight or dimensional weight (Length x Width x Height / 139 or 166). Our auditor flags every box where DIM weight exceeds actual weight.
Does Thermallabelstudio upload my customer shipping addresses to any cloud server?
No. All label coordinate calculations and shipment manifest rows execute 100% locally in your browser RAM, keeping buyer names and street addresses completely private.
How does Thermallabelstudio compare to LabelResizer ($15/mo) and AZLabels ($15/mo)?
Instead of paying $180/year or hitting monthly label quotas, you get unlimited local 4x6 batch cropping and DIM weight auditing for a $19 one-time lifetime buyout.
