In our demo https://bryntum.com/products/scheduler/examples/export/
In console

scheduler.features.pdfExport.export({
  exporterType: 'multipage',
  fileName: 'Plataine-scheduler',
  fileFormat: 'pdf',
  orientation: 'landscape',
  scheduleRange: 'currentview',
  repeatHeader: true,
  sendAsBinary: true,
  })

In result pages

are not fully filled, there is a space in the end on many pages
