Why Cable Printing Isn't on iPhone
iOS handles printing strictly via Bonjour discovery and IPP Everywhere (AirPrint over Wi-Fi). Unlike macOS, iOS does not include arbitrary third-party USB host drivers or CUPS filters over Lightning/USB-C cables.

Most wireless printers enforce a mechanical gripper margin (typically 0.17" to 0.35"). This studio places visual bounds and cut lines inside the unclipped area so barcodes and headers never get cut off.
Standard web prints print saturated colors as muddy gray grids. The High-Contrast Ink-Saver toggle transforms fills to crisp black vector lines, reducing ink consumption and speeding thermal printing.
1. Tap the "AirPrint / Print" button above from Safari or Chrome on your iPhone or iPad.
2. The native iOS AirPrint dialog appears with your printer selected via Wi-Fi.
3. Confirm paper size (Letter, A4, or 4x6) matching your tray. Since margins are already calculated, you can leave scaling at 100% without worry of stray blank pages.
Mobile AirPrint sends raw raster jobs over wireless IPP Everywhere, where consumer printers enforce mechanical gripper margins around physical paper edges. When you increase the safe margin slider, the studio recomputes safe width and height, shifting corner crop marks and constraining the printable bounds inward. Document titles, high-contrast barcodes, and data blocks scale proportionally inside the safe box, ensuring complete legibility without hardware edge truncation.
