Laserjet Enterprise M507

I purchased an Amazon return LaserJet Enterprise M507.  I just need to install the drivers and use it but when I use the HP website to download the installer packet I get this error message. HP-DQEX5.exe Hard drive on this computer to continue enter an admin password PCOCLNKO/ADMIN

 

I have not idea what it's asking for??  Was this a password that someone else created on the printer and now it's locked?  Is this something on my computer, a file I can access?  I'm lost.  Help!
