You should not setState within a setState callback function. Instead it should return the new state. This:

onHandlePrint = (pdf) => { this.setState({pdf}, () => { this.setState({pdfStatus: true}) }); }; 

should be:

onHandlePrint = (pdf) => { this.setState(() => {pdf, pdfStatus: true}); }; 

But really if you don't need to…
