ARCWorks Simple Receipt Printer 1.0.1

A robustness and privacy patch based on feedback after the first public release. The approved receipt appearance and paper layout are unchanged.

Fixed

  • Restores the last selected receipt template on the next launch
  • Skips malformed or temporarily unreadable template files instead of crashing at startup
  • Validates imported template JSON before copying it into the application folder
  • Disables Print and Print Preview when no valid printer is available
  • Prevents simultaneous application instances from racing on local receipt-number state
  • Keeps business identity in JSON templates rather than compiled model defaults
  • Replaces key receipt-layout magic numbers with named constants

Resource handling

The reported logo GDI+ leak was already fixed in the v1.0.0 source (using var logo = Image.FromFile(...)). Version 1.0.1 adds a regression test that renders the logo and confirms its file handle is released immediately afterward.

Validation

  • Regression tests: 3 passed
  • Release build: 0 warnings, 0 errors
  • Approved four-up preview: visually unchanged
  • Inno Setup 6.7.3 compile: passed
  • Installer install, application launch, and uninstall: passed
  • SHA-256: B1E5AF237D7434B077BE2CF7E27DA480DC2F53A62D757A6AD1C71C2F53E8A528

Windows may show an Unknown publisher warning because the installer is not digitally code-signed.
