Leslie V. 0 Report post Posted August 15, 2019 Hello Brent, Thanks for contacting Nitro! Unfortunately, Microsoft has changed the way the 'Print Spooler' works in Windows 10. Because of this, Nitro Pro 9 cannot be supported on Windows 10. The PDF Creator built into Nitro Pro 9 will not work properly. Though other functions should remain usable. You have two options from here: 1. You could upgrade to Nitro Pro 12: https://www.gonitro.com/pro/upgrade 2. You could install Nitro Pro 12 as a trial (alongside your current installation), just to use the PDF creator. The Creator will remain after the trial has finished. Hope that helps!

danielniro 0 Report post Posted October 30, 2019 I also faced the same printer connecting problem. I thought it was a printer driver problem and updated the system driver but new issue Canon Printer Error 5200 message shown on my system. I want a proper solution to fo those issues.
