AirPrintBridge_Setup_v1.3.0

v1.3.0 - 2026-09-11

🎯 Dynamic Media Size Handling & Label Printer Scaling Fix

• IPP Media Attribute Parsing: Implemented structured binary IPP job attribute extraction (extract_ipp_job_attributes) to parse client-selected paper sizes such as media keywords (e.g., iso_a6_105x148mm, na_index-4x6_4x6in).
• Physical Media Dimensions Mapping: Added IPP_MEDIA_SIZES lookup mapping standard PWG media keywords across ISO A/B/C series, North American formats, and label/receipt sizes directly to millimeter dimensions.
• Windows DC DEVMODE Configuration: Dynamically adjusts the printer Device Context DEVMODE (DMPAPER_USER with PaperWidth and PaperLength in tenths of mm) via ResetDC(), ensuring Windows spooler respects the requested paper format.
• True DPI-Aware 1:1 Scaling: Replaced canvas-dependent stretch scaling with native DPI rendering (printer_dpi / 72.0), fixing the issue where A6 and thermal labels printed significantly smaller on label printers (such as Zebra ZD220D). Includes automatic shrink-to-fit safety clamping.
• Expanded Media Advertisements: Advertised A5, A6, A7, A8, US Legal, 4×6", and 100×150mm formats in media-supported and media-ready attributes so iOS and Android dialogs present label sizes natively.

AirPrintBridge_Setup_v1.2.0

v1.2.0 - 2026-08-18

📱 Android & IPP Everywhere Full Compatibility

• UUID Synchronization for Android BIPS: Synchronized the printer's UUID in mDNS TXT records with the printer-uuid IPP response attribute (uuid5(NAMESPACE_DNS, f"{printer_name}@{hostname}")). This resolves the strict UUID mismatch rejection in Android's Built-in Print Service (com.android.bips), allowing Android devices to natively discover and show the printer.
• RFC 8011 IPP Tag Compliance: Fixed encoding of uri-security-supported and uri-authentication-supported to IPP_TAG_KEYWORD (0x44), matching IPP RFC standards and Android native C parser expectations.
• Expanded PDL Support: Added image/pwg-raster to both mDNS TXT pdl records and IPP document-format-supported attribute lists for complete Android IPP Everywhere / Mopria standard compliance.

🔍 Diagnostic Tooling

• Android PDL Validation: Updated diagnose.py to test and report PWG-raster / Android PDL format readiness during network diagnostic scans.

v1.1.1

v1.1.1 - 2026-08-12

🌐 Multi-PC Network & Display Enhancements

• Multi-PC Network Identification: Dynamic printer naming incorporating host PC name and printer name (Printer (PC-NAME)).
• Unique mDNS UUIDs: Machine-specific mDNS UUID generation (uuid5 on Printer@Hostname) preventing iOS/AirPrint device collision across multiple PCs running the bridge on the same LAN.
• Enhanced IPP & mDNS Attributes: Updated printer-make-and-model, printer-info, printer-location, and mDNS TXT note fields for clear printer discovery UI on iOS, macOS, and Android.

v1.1.0

v1.1.0 - 2026-08-12

🛠️ Windows Service & Compatibility Fixes

• Windows Service SCM Error 7039 Fixed: Updated PyInstaller build settings to --console mode to ensure PID consistency with Windows Service Control Manager.
• Persistent Service Logging: Fixed log file path resolution when frozen with PyInstaller (sys.executable directory) so logs persist properly.
• IPP Operation Expansion: Added support for Get-Job-Attributes (0x0009) and Cancel-Job (0x0008) required by iOS PrintKit post-print routines.

AirPrintBridge_Setup_v1.0.1

v1.0.1 - 2026-08-11

🐛 Bug Fixes

• Interactive Mode Fallback: Fixed an issue (Error 1063) where running the standalone executable directly would crash. It now gracefully falls back to interactive debugging mode if it's not launched by the Service Control Manager.
• Documentation: Added troubleshooting steps for users with virtual printers (like RustDesk) that take over the Windows Default Printer setting, causing jobs to print to nowhere.
