Automatic duplex printing no longer available on my HP Envy

Hi, hope someone can help.

Overnight, my printer has stopped doing automatic duplex printing on PDF documents. It is an HP Envy 4520.

I have not made any changes to hardware or software/or done any upgrades etc. I use Windows 10. I have tried to update the device driver but it is up to date.

I have tried using the HP smart app as seen on another thread but it still requires me to manually move the paper to print the second side. 

Under printer properties it says double sided but if I look under device settings it now says 'not installed' next to 'automatic duplexing unit. 

I have not had this problem previously, and it was doing automatic double sided printing 2 days ago!

Any suggestions?

Thank you!

    Well you are lucky because mine stopped printing double sided (I have Envy 4500 series) and first said to do it manually and never offered the double sided and now it doesn't even say do it manually.  It only has basic printing.  No idea why.  I can't find anyplace in devices and printers where it even indicates that I have double sided printing offered up.  I have had this printer for years and it has always printed double sided if I wanted.

    I am using a PC here not laptop or mobile so when you talk about changing ports I'm not sure where you mean.

    I have just discovered that my HP Envy 4500 no longer prints double sided as well.  I have done nothing to change it but now it offers just the normal printing and I can manually do it which is nonsense.  No idea why this changed or what to do about it.  Seems this has happened to several people so perhaps this is due to the Windows 10 update?

    Thank goodness I decided to see if anyone else had this weird problem today after several months of irritation! The change to LPT2 worked for me (?? not LPT1 nor LPT3!!). So many thanks to everyone who located this fix. Very Grateful.

    Brilliant! yes that worked for me also. It has been bugging me for weeks, having upgraded to Surface pro.
