If you pass the exam center should provide you with a provisional pass(and no score) printed there and then(I’ve sat three and that has always been the case).
If you fail, I beleive you will be provided with a score broken down by domain.
If it doesn’t say anything or it was because of ISC2 some pure guesses, network was down or too slow, it was selected for audit or something else. But it it was just printer down then they owe you a print out, however ISC2 should also email you a pass/fail.
If you were doing the CISSP via CAT and you were given an limited number of questions you might infer that a pass was more likely than a fail(based on hearsay). Bottom line you should email member support with your candidate number and ask them what the status is.

Important Information on (ISC)² Exams
One of the benefits to candidates taking an examination via CBT is that most candidates receive their scores immediately upon completing their examination. In some cases, however, in order to ensure it is providing accurate and valid test results, (ISC)² must conduct periodic psychometric analyses before it can release exam results. For the small number of candidates affected by this process, the candidates will receive their results within 4-6 weeks after taking the exam. (ISC)² apologizes in advance for inconvenience to those candidates who will not receive their pass/fail status at the test centers.
Even if your exam attempt is selected for additional psychometric analysis you still get a printout at the end of the exam letting you know what's going on - this happened to me when I took my CISSP exam.
This only seems to occur when exams have been updated and applies to the first x number of people who sit the new test. Their results are held back so ISC2 can be assured the new exam is fit for purpose. I assume if everyone who sat the test failed they'd know the new test is too hard, while if everyone passed they'd know it's too easy, etc. etc.
I think in this case the reason for no printout having been issued was just simply an issue with the test centre's printer.
