Answer 1

Try:
Print(){
let options: PrintOptions = {
name: 'MyDocument',
printerId: 'printer007',
duplex: true,
landscape: true,
grayscale: true
};
//Checks whether the device is capable of printing
this.printer.isAvailable().then(()=>{
console.log("printer available")
}).catch((error)=>{
console.log("printer not available"+error);
});
}
