That looks like something very different. No 4017 but a ULN2803 driver.

Sure you are getting 12V from the parallel port? I never saw one that
did that.

And you won't - they are TTL. But the 2803 et al are TTL-compatible input.

Note the data *** at http://www.analog.com.tw/DB/pdf/DS-2003-02.pdf shows a
solenoid driver config on p1.
