there seems to be a problem with the time zero value of that pulse
try "VCC 10 0 PULSE(0 8 1p)" instead. maybe "(0 8 0 1p)".
(not sure if this is a bug or a feature. spice implements some guessing
around zero-time transitions...)

the tran command will care of that. there should be no difference if you
leave it out.

in gnucap, the .print command actually attaches probes to the circuit.
after the simulation it's too late. but i think, generally, you can run
a simulation, attach probes, then continue.
maybe you want to try this instead
.TRAN 0 {start_print} {start_print/10}
.print tran v(nodes) v(VCC)
.TRAN {stop_time} trace=a
have fun
