Actually, my firm left Intuit.  We have a new software provider.  This issue wasn't the only thing, but it was certainly one of the big issues.  We aren't on Lacerte either.  We went to a new company.  And as you can expect, yes this new software prints the firm name or preparer name (our choice) on the signature line of the 8879.

We were extremely disappointed with Intuit and the way they handled things like this.

Honestly it still blows my mind how Intuit just doesn't understand this.
