v1.3.0: Add Scale Control for PDF Printing

🚀 New Features

Print Scale Control

• API Scale Parameter: All printing endpoints now accept an optional scale parameter to control PDF scaling
• Scale Options:
  • noscale - Original size (default)
  • shrink - Shrink to fit printable area
  • fit - Stretch/shrink to fit entire paper

Updated Endpoints

• POST /print-url - { url, documentType, copies, scale }
• POST /print-data - { pdfBase64, documentType, copies, scale }
• POST /print - { url, scale }
• POST /print-both - { invoiceUrl, labelUrl, invoiceScale, labelScale }

📚 Documentation

• Updated API documentation with scale parameter examples
• Added scale selection to testing interface
• Enhanced code examples with scale usage

🔧 Technical Details

• Fully backward compatible - defaults to noscale if not specified
• Invalid scale values gracefully fall back to noscale
• No changes required to existing integrations

💡 Example Usage

fetch('http://localhost:9000/print-url', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({
        url: '[https://example.com/invoice.pdf'](https://example.com/invoice.pdf'),
        documentType: 'invoice',
        scale: 'fit'  // New parameter
    })
})
