How to Evaluate Terminal Print Performance
The printing performance of the terminal is as follows:
Column 3 shows how long it took the program to call the print method until the paper started moving.
Column 4 shows how long it took the program to call the print method until the print is complete.
Q2:
| print method | receipt length | paper begin to move (s) | print finish/method return (s) | feeling speed (mm/s) |
|---|---|---|---|---|
| printText | 60 lines/~30 cm | 0.1 | 5.5 | ~54 |
| printText | 120 lines/~60 cm | 0.2 | 11.3 | ~53 |
| printBitmap | 25 cm | 0.3 | 3.6 | ~69 |
| printBitmap | 50 cm | 0.4 | 7.6 | ~66 |
| printBitmap | 75 cm | 0.6 | 11.6 | ~65 |
| printHTML | 25 cm | 1.3 | 4.7 | ~53 |
| printHTML | 50 cm | 1.5 | 8.8 | ~57 |
| printHTML | 75 cm | 1.6 | 12.7 | ~59 |
