Virtual Printer App ( Beta v1.0.1 )

Project Enhancements Done (April 10 ,2025 - April 21, 2025)

Core Functional Improvements

• IPP Server:

  • Built an IPP stub server using NanoHTTPD running on port 3000.
  • Implemented request logging and job saving logic.
  • Added minimal binary IPP response.
  • Saved incoming IPP data with timestamped filenames (and handled EROFS issues).

• NSD (Network Service Discovery):

  • Broadcasted printer as _ipp._tcp on port 631, but mapped actual traffic to port 3000.
  • Registered NSD correctly using Android's NsdManager.
  • Confirmed visibility using dns-sd -B _ipp._tcp.

💡 Compose UI + Navigation

• Introduced Bottom Navigation with 3 Tabs:

  • 🏠 Home – Overview & printer status

  • 🖨️ Print – Start/Stop printer + configure name

  • 🐞 Debug – View request logs, clear logs

• Status updates now persist across navigation tabs via PrinterViewModel.

Tab	Preview	Description
🏠 Home		Overview & Printer Status
🖨️ Print		Start/Stop Printer + Configure Name
🐞 Debug		View Request Logs, Clear Logs

🧰 Technical Setup Fixes

• Fixed Gradle dependencies in libs.versions.toml.
• Corrected Kotlin Compose compiler setup.
• Ensured consistent Compose Material3 usage and navigation integration.

🛠️ Debugging & Runtime Logging

• Added detailed log capture from IPP server into a Composable view.
• Handled multiple POST requests and displayed captured byte sizes in logs.
