How to Evaluate HTML Printing Function Performance

From wizarPOS

Initial Bitmap Generation from HTML:

  • First Use: Approximately 1 second to generate a bitmap from HTML.
  • Subsequent Uses: Each subsequent generation takes about 0.5 seconds.

Performance in Different Scenarios:

  • Printing 60-Line Tickets:
    • Start Time: Printing begins 1 second (or 0.5 second) later than in text mode.
    • Stop Time: Printing ends 0.5 second (or 0.2 second) later than in text mode.
  • Printing 120-Line Tickets:
    • Start Time: Printing begins 1 second (or 0.5 second) later than in text mode.
    • Stop Time: Printing ends 0.5 second earlier than in text mode.
  • Printing 70cm Tickets:
    • Preparation: Ready to print the image in approximately 1.5 seconds.
    • Total Printing Time: Around 13 seconds.

Optimization Strategies:

  • Content Simplification: Keep HTML content as straightforward as possible.
  • Tag Management: The number of tags in HTML affects bitmap rendering speed. Use the minimum number of necessary tags.
