How to Evaluate HTML Printing Function Performance

From wizarPOS

Performance description

  • It takes 1 second to get the bitmap from HTML for the first time, and 0.5 seconds for each time later.
  • In the case of printing 60 lines of tickets, the printing start time is 1 second or 0.5 second later than the text mode, and the printing stop time is 0.5 second or 0.2 second later than the text mode.
  • In the case of printing 120 lines of tickets, the printing start time is 1 second or 0.5 second later than the text mode, but the printing stop time is 0.5 second earlier than the text mode.
  • We have tested the printing length of 70cm ticket. It is ready to print the image in 1.5 seconds. The total printing time is 13 seconds.

Optimization strategy

  • Make HTML content as simple as possible.
  • The number of tags affects the speed of rendering bitmaps from HTML, so use the necessary (as few as possible) tags in HTML.
