I am looking at this and the hold up is I can't remember the protocol 
readIPPResponse() is
trying to follow. Without that understanding it is hard to say much .. 
so I need to go read
up and remember ..

Two  comments : There is an extra space in

if (responseMap.length>   1) {

The test update is bogus in referring to this bug. The change is nothing 
to do with the bug.
And I actually prefer printer tests to throw nasty exceptions when there 
are no printers
and they need one ... else SQE just don't configure printers on test 
systems and the tests all wrongly pass.
Would you run Linux UI tests on a blade with no X-server running ?
