And just to add up to Rainer's excellent explanation, as a rule of
thumb, I usually use a PrintStep of ten times the Time of the
simulation. Mileage may vary, depending on how stiff your model is. I
can go as low as 5 times, but resolution becomes poor. Below 2 times I
definitely get skipped events, therefore some catastrophic result. It is
recommended to test different values, to graph the output (using grace
for instance) and check if everything is alright. Our models heavily use
events and oscillators and so far we never had any issue when using a
PrintStep of at least 10 times the total simulation Time.

Hope this helps,
Eric
