Version 1.4.2

Added

• Custom in-app dialogs (js/dialog.js) — replaces native Windows OS confirm/alert popups with dark-themed modals matching the app UI. Used for all destructive confirmations and error messages across History, Logs, and API Docs pages.
• Working Clear History — DELETE /print-history server endpoint added; button on History page now fully functional. Deletes all monthly stats files while preserving the migration marker.
• Automated test suite (59 tests, no printer required) — Jest + Supertest covering:
  • monthlyStats.js: addPrintJob, getPrintHistory, getStatisticsForDateRange, getAvailableMonths, getMonthlyReport, clearHistory, migrateFromPrintHistory
  • configStore.js: defaults, get/set, persistence
  • server.js: all API routes including pagination, filtering, and clear

Changed

• History page pagination — loads 100 records at a time with a "Load More" button instead of fetching all records at once (was loading 25k+ records into memory). Type/status filters are server-side; date filters apply client-side on loaded records.
• History page summary stats — Total Jobs / Successful / Failed counters now pulled from /statistics for accurate all-time totals regardless of what page of records is loaded.
• /print-history API — now accepts limit, offset, documentType, status query parameters and returns total and hasMore alongside the jobs array.
• Status & History pages — 3-card indicator rows now forced to a single row (repeat(3, 1fr)) with compact sizing; previously the third card would wrap to a second row.

Internal / Developer

• Refactored server.js: moved all Express routes into createExpressApp() and exported it for testing — no production behaviour change.
• Added __mocks__/electron.js and jest.config.js for test infrastructure.

MicroPrint 1.3.3 – Reliable Label Scaling & API Cleanup

• Reliable label shrink‑to‑fit

  • All label prints now go through SumatraPDF with paperkind=256,shrink, matching the known‑good CLI behavior.
  • Applies to both URL (POST /print-url) and base64 (POST /print-data) label flows.

• Consistent across dev and installed builds

  • New resolveSumatraPath() helper locates Sumatra from:
    • Dev: node_modules\pdf-to-printer\dist\SumatraPDF-3.4.6-32.exe
    • Packaged app: resources\app.asar.unpacked\node_modules\pdf-to-printer\dist\SumatraPDF-3.4.6-32.exe
    • Plus standard Program Files\SumatraPDF\SumatraPDF.exe locations.

• Label options simplified

  • For documentType: "label", API scale / paperSize are ignored; labels always use a fixed shrink‑to‑fit label mode.
  • Invoices and generic PDFs still honor scale (noscale/shrink/fit) and paperSize.

• API surface and docs cleanup

  • Removed legacy and unused endpoints:
    • /print, /print-both
    • /pdf-list, /sample-pdfs
    • /api/status, /history, /stats, /api-docs, /api-examples, /status-check, /test
  • api-docs.html now documents only:
    • POST /print-url, POST /print-data
    • GET /printers, GET /settings, POST /settings
    • GET /status, GET /print-history, GET /statistics
  • Docs explicitly note that labels always use paperkind=256,shrink internally.
