vue项目中如何利用LodopFuncs插件实现pdf批量打印功能？

printingShopee() {
  const strURL = [] // pdf文件流
  const strURLorContent = strURL.map(item => window.atob(item))
  LODOP = getLodop()
  LODOP.PRINT_INIT('打印')
  LODOP.SET_PRINT_PAGESIZE(3, 1000, 1500, '')
  for (let j = 0; j < strURLorContent.length; j++) {
    this.creatPdfRage(strURLorContent[j])
  }
  LODOP.SET_PREVIEW_WINDOW(0, 0, 0, 0, 0, '')
  if (LODOP.SET_PRINTER_INDEXA(1)) {
  LODOP.PREVIEW()
},
creatPdfRage(pdf) {
  LODOP.NewPage()
  LODOP.ADD_PRINT_PDF(0, 0, '100%', '100%', pdf)
},
