Converting ZPL print stream into a PDF file

Question

Is it possible to convert a ZPL print stream into a PDF file? If so, how can this be done?

Answer 1

You can use the Labelary web service. Normally it would give you a PNG image:

wget "http://api.labelary.com/v1/printers/8dpmm/labels/4x6/0/^xa^cfa,50^fo100,100^fdHello World^fs^xz" -O label.png

But it will give you a PDF file if you send the right Accept header:

wget "http://api.labelary.com/v1/printers/8dpmm/labels/4x6/0/^xa^cfa,50^fo100,100^fdHello World^fs^xz" --header="Accept: application/pdf" -O label.pdf

Answer 2

The only way to do it is to save the ZPL preview as an image and then convert the image to a pdf.
