Most if not all recent HP printers are designed to
be left powered up, free to go in to and out of
standby as necessary. In standby mode, the power
drawn is tiny -- as low as 1 watt/hour.
But if you power the printer down, it does not know
what state it was in when it was shut down, so it
will run a clean and align cycle of necessity. This
also uses a lot of ink over time.
Have you considered not hitting the power button?
After printing the alignment page place it on the scanner glass in the
orientation specified and press the "scan" button to complete the alignment.

True.

This is partially true. If the power is removed from the printer with an
external switch or pulling the plug it will perform a more aggressive
cleaning cycle on the next power on. I do not know of any HP printers that
will lose alignment information in this case. Using the printer's power
button to power off the printer will not require more servicing when the
printer is powered on. (But... if the printer power is removed externally
even after it has been turned off with the printer's power switch it will do
a more complete servicing cycle when turned on. Te printers have an
internal clock and keep track of the time since the last print job, and use
this information to do an appropriate amount of servicing. If you remove
the power with an external switch the clock will lose track and the printer
will assume the worst case.

Simple, my dear Watson! (When you know how.)
