Yes, you're right. The search box itself prints, but the query inside the box is missing. The query does show on my printed page, up in the top margin as the title of the page... eg...
query terms - Google Search . . . Page x of y
...but that may depend on how your print options are set up.
I notice, btw, that the formatting of the individual listings of the serp is finally coherent... previously the underlined titles seemed to float away from the snippets and url... so Google may be working on the print style sheet in general.
