Software Fix - Ultra Print

Often, Ultra Print is fine—the Windows driver is the culprit. Ultra Print sends raw data (ZPL, EPL, or ESC/P) directly to the printer. If a Windows update changed the driver type, the printer will ignore the commands.

// PrintJobManager.js
class PrintJobManager 
  constructor() 
    this.jobList = [];
// Add a new print job to the list
  addJob(job) 
    this.jobList.push(job);
    this.renderJobList();
// Update an existing print job
  updateJob(jobId, priorityLevel, scheduledPrintTime) 
    const jobIndex = this.jobList.findIndex((job) => job.id === jobId);
    if (jobIndex !== -1) 
      this.jobList[jobIndex].priorityLevel = priorityLevel;
      this.jobList[jobIndex].scheduledPrintTime = scheduledPrintTime;
      this.renderJobList();
// Render the job list
  renderJobList() 
    const jobListElement = document.getElementById('job-list');
    jobListElement.innerHTML = '';
    this.jobList.forEach((job) => 
      const jobElement = document.createElement('div');
      jobElement.textContent = `$job.id - $job.priorityLevel - $job.scheduledPrintTime`;
      jobListElement.appendChild(jobElement);
    );
// Create a new PrintJobManager instance
const printJobManager = new PrintJobManager();
// Add event listeners for user interactions
document.getElementById('add-job-button').addEventListener('click', () => 
  const job = 
    id: Math.random(),
    priorityLevel: document.getElementById('priority-selector').value,
    scheduledPrintTime: document.getElementById('schedule-selector').value,
  ;
  printJobManager.addJob(job);
);
document.getElementById('update-job-button').addEventListener('click', () => 
  const jobId = parseInt(document.getElementById('job-id-input').value);
  const priorityLevel = document.getElementById('priority-selector').value;
  const scheduledPrintTime = document.getElementById('schedule-selector').value;
  printJobManager.updateJob(jobId, priorityLevel, scheduledPrintTime);
);
