Connect Sony Alpha 6000 → Raspberry Pi → Print on Template (Wireless)

Hi,

I'm building a photo printing experience where I capture guests' pictures on-site and print them on predefined newspaper templates in real-time. Here's the workflow:

1. Capture: I take photo of guest with Sony Alpha 6000
2. Transfer: Image transfers wirelessly to Raspberry Pi
3. Template: Photo is placed in exact position on HTML/image template
4. Print: Raspberry Pi sends output to Epson EcoTank ET-4950 (via WiFi/USB)

Requirements:

• No cables between camera and Pi (wireless connection only)
• Sub-30-second end-to-end process
• Reliable, repeatable workflow

Questions:

• Best wireless method for camera-to-Pi transfer? (WiFi Direct, FTP, SD card reader?)
• Any experience with Sony Alpha 6000's wireless capabilities?
• Recommended Python libraries for image positioning on templates + printing to Epson?
• Has anyone done something similar with event/on-site photography workflows?

Any pointers appreciated. Thanks!
