How to Evaluate Terminal Print Performance

Objective:

This document provides a detailed analysis of the terminal's printing performance, focusing on the time efficiency of the print process.

Performance Metrics:

1. Initiation Time (Column 3):
   • Description: This metric indicates the duration from the moment the print method is called to when the paper starts moving.
   • Purpose: It helps in assessing the response time of the printer after receiving a print command.
2. Completion Time (Column 4):
   • Description: This metric shows the time taken from the initiation of the print method until the completion of the printing process.
   • Purpose: It evaluates the overall efficiency of the printing process, from start to finish.
