If it's a one-off situation, as opposed to something that should be part of your long-term test cases? Then yes, using print-statements is fine. Everyone does it, this isn't (or shouldn't be) controversial. Sometimes a series of print-statements are better for helping you understand exactly when and how a bug occurs. This is particularly true in situations where the debugger is difficult or impossible to use (e.g., multi-threading). Of course, in that situation, logging may be better, but that's just glorified printf.
