looks like the library is loaded ... so what is your test
we don't do png, we do outlines (actually native zint graphic structures that we then convert with mp)

Hi Hans,
here is the example that I used, basically I took it from the from the module:

\starttext
\usemodule[zint]
    \startTEXpage
        \barcode[alternative=PDF417,text={Hans Hagen}]%
        \blank
        \barcode[alternative=pdf417,text={Ton Otten}]%
        \blank
        \barcode[alternative=ISBN,text=9789490688011]%
        \blank
        \barcode[alternative=isbn,text=9789490688011,width=3cm]%
        \blank
        \dontleavehmode
        %\barcode[alternative=qr code,text={This is ConTeXt MKIV : #1}]
        \barcode[alternative=qr code,text={This is ConTeXt LMTX}]
        \barcode[alternative=qr code,text={\input{tufte}},width=3cm]
    \stopTEXpage
\stoptext

The resulting PDF has just empty page

Best regards,
Ivan
