The example cannot print pdf

[2vl]

func main() {

The example cannot print pdf ,

After running, the printer queued up with documents and soon disappeared, but the printer did not respond.

Does it have anything to do with the printer? I don't know why.

This code heavily relies on the printer's ability to read a PDF. If PDF printing does NOT work, try a simple TXT file which from what I know should work in all cases. If your printer cannot read the PDF language, it will not be able to print the PDF.

Maybe postscript is needed

so take the pdf and reverse it to postscript using Ghostscript ?
