Are you using Basic or thinking about using Basic?

On the screen to Print in Professional, there's a box to Mask Client, Im not fluent in Basic, Im not sure if they have the same option, their print set up is different than Professional...I took a quick glance but I didnt see it.

Hi @RobinP 
Thanks for posting your question! Here’s a support article that may help with this:
Masking and unmasking sensitive data in ProSeries

It says "ProSeries Basic can mask data on-screen, ProSeries Professional can mask data on-screen and when printing."

If you need further assistance with this we would reach out to ProSeries Support, as they can best help with your specific situation.
Looking forward to seeing more of your contributions in the Community!
