Sidecar Printer: print to your iPad or iPhone from all your favorite Mac applications.
Reading documents from your Mac on your iPad or iPhone is as simple as File → Print (or ⌘P ⏎). Sidecar Printer turns your iPad or iPhone into a paperless Wi-Fi printer that works from any printing Mac app.
Sidecar Printer can share PDFs of your documents with other applications like iBooks, or over email. When you need a paper copy, you can print directly to AirPrint-compatible paper printers.
