How to Evaluate HTML Printing Function Performance

Performance

• Usually it need 1 second to get the bitmap from HTML at the first time. In the next time, it only need 0.5 seconds.
• In the case of a 60 lines receipt, the printer starts 1 second or 0.5 seconds slower than the same text mode printing. And the printing stops 0.5 seconds or 0.2 seconds slower than the text mode printing.
• In the case of a 120 lines receipt, the printer starts also 1 second or 0.5 seconds slower than text mode printing. But the printing stops 0.5 seconds faster than text mode printing.

Optimization strategy

• Keep HTML content as simple as possible.
• The number of tags affects the speed of rendering bitmap from HTML, so please only use necessary tags in the HTML.
