Your title leads me to ask a question. Does something on the printer actually BLINK when this problem occurs? And if so, does the printer have some kind of status display that might show an error? Since it appears that the printer is the thing that is balking and not Access, look to the front of the printer first.
Second question, independent of the first (mostly). Is the printer hard-wired or Wi-Fi? If you check the computer's printer queue, are the files still pending in the queue? If so, what is their status? (The point of the latter questions is that it might be possible to look elsewhere for an error code.)
