if I ask ns1/2/3/4/5/6.hp.com directly for AAAA for onramp01.hpeprint.com.:

; <<>> DiG 9.8.1-P1 <<>> AAAA onramp01.hpeprint.com. @ns6.hp.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 30318
;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 6, ADDITIONAL: 6
;; WARNING: recursion requested but not available

;; QUESTION SECTION:
;onramp01.hpeprint.com.         IN      AAAA

(I get the same result for all ns hosts)

if I ask my local bind (ubuntu package == 1:9.8.1.dfsg.P) though I get:
$ dig AAAA onramp01.hpeprint.com @localhost

; <<>> DiG 9.8.1-P1 <<>> AAAA onramp01.hpeprint.com @localhost
;; global options: +cmd
;; connection timed out; no servers could be reached

That's a bit weird and frustrating.

scott's request LOOKS like  a request to 'some resolver' (not directly
to them, perhaps his local bind instance?  I wonder why 8.8.8.8
returns srvfail? I think one of the google-public-dns people reads
nanog, perhaps he knows? (or could fix this which seems to be a bug,
to me at least)
