Hello,
Hopefully the following info will be helpful.

I am using a stand alone computer Windows 10, 32 bit PC desktop.
PS was printing fine earlier, then after an update for some states (PS), I no longer am able to print to my Vault or on the printer.
Other PDF's print fine. Printer is up to date.
I was sometimes getting a pop-up box that said "can not convert empty PRintList ML',
As the others have said, it just prints blank pages.
When printing to my SmartVault, it only transferred the Diagnostics page.
All forms are released and ready for print. I printed these forms earlier in the day.
Windows was checked today for updates and is currently up to date.
Checked ProSeries and it is also up to date.
Brother printer is up to date.
Also, I just tried to restarted my computer, but with the same results.
I saw another post that said i need to reinstall .NET framework...which is "to be done by an IT professional"? Think I'll pass on that right now....
Any help would be appreciated...In the meantime, I will see if I can get through to support.
