Bluetooth Receipt and Label Printing for iPad
Embedded the client's existing web app into a native iOS web view, i.e., WKWebView, using WebKit. I connected it to Bluetooth devices via the JavaScript bridge when the web app requested. I saved login information for a seamless experience. Receipts and labels from PDF to native CGImages were rendered to send to Zebra printers using the Zebra printer software developer kit (SDK).
