python - 使用 Python CUPS 时打印速度慢

Question

当我尝试使用 CUPS 和 xhtml2pdf 库打印文档时 - 一切都很好，但打印速度非常慢。这个问题有解决办法吗？

这是 Python 代码:

import cups
from xhtml2pdf import pisa

def main():      
  filename = "/home/stopfan/print.pdf"    

  xhtml = "<h1>Test print</h1>\n"
  xhtml += "<h2>This is printed from within a Python application</h2>\n"
  xhtml += "<p style=\"color:red;\">Coloured red using css</p>\n"
  xhtml += "<h1>Test print</h1>\n"
  xhtml += "<h2>This is printed from within a Python application</h2>\n"
  xhtml += "<p style=\"color:red;\">Coloured red using css</p>\n" 
  pdf = pisa.CreatePDF(xhtml, file(filename, "w"))
  if not pdf.err:

         pdf.dest.close()

         conn = cups.Connection()
         printers = conn.getPrinters()
         for printer in printers: 
                print printer, printers[printer]["device-uri"]
                printer_name = printers.keys()[0]
                conn.printFile(printer_name, filename, "Python_Status_print", {})
  else:
         print "Unable to create pdf file"
if __name__=="__main__":
  main()

问题出在司机身上。尝试在 Windows 上运行它，一切都很好。
