Hi all
I am working on app which use printing and sharing functionality. I have setup both printing and sharing successfully i.e working fine in Android but not work in iOS. in IOS it behave strange. it work when I click on print icon and after that again click on status bar again. Please suggest what i am doing wrong here.

   let printData = this.printContent(); 
  this.printer.print(printData).then(function()
  {
   
  },
  function()
  {
     alert("Error while printing!");
  });

hi , before print data you must check if printer is available ,

you can use :
isAvailable() and check()

Should i also do for sharing also because sharing also has same issue.

Should i also do some thing for sharing also

this.socialSharing.share("",""+this.record.orderNo+" Sale Order",folderpath+"/"+filename,null).then(() => {

}).catch((error) => {
  // Error!
  alert(error);
});
