I don't know which app this is, but there are a number of them.
However, it is not a good idea with many inkjet printers.
Firstly, you would have to keep the printer "on" all the time, or turn
it on with a power bar, which is also not a good idea.
Some inkjet printer require a complete shut down to seal the heads.
Other printers have an "off timer" and will, on being turned on, go
through a complete cleaning cycle. These cleaning cycles use up 2-5% of
the ink in the cartridge per cleaning. SO, if you don't need the printer
that day, you have used up a lot of ink for very little benefit.
Unless you are in a very warm/dry climate, or your printer has a bad
capping mechanism, or bad inks, it should be able to handle lack of use
for weeks or months at a time with clogging. If you are talking about
the printer sitting for over 3 months, then, yes, a cleaning cycle or a
test print makes sense during that interval.
