No, it would be obvious in the logs if you used conquest printer.
This one shows update time and source in the caption, there are 3 sources, socket updates (lines added more and log more than 0.1s older than last print), scroll update (over 1100 lines in log), and timer updates (timer ticks and log more than 0.1s older than last print). In my system it mostly ends on a timer update.
