I will give you my not-quite-similar issue and my work around. I like printing the Client Copy with masking the SSNs, etc, and it has a watermark on ALL the forms. I do NOT want watermarks on the 8879, 1040V, 1040ES, however, but if I print them all at once with masking they all have masking and watermarks. So my Print Return parameters for Client Copy do NOT include those forms. Ctrl Y changes those parameters.

I have to manually print those forms separately. This is different from prior years before we had masking.

When I sent 8879s to clients with masking and "Do Not Mail" or "Taxpayer Copy" watermarks, the clients called to ask if they could be mailed, like the 8879s to me and the 1040ES and 1040V to the government. That is not how it should work.

ps Prior to masking, I set the Print All parameters so the 8879, 1040V and 1040ES printed first, then the Slip sheet, then returns. I separately print the letters since I use colored paper for those.
