All printers are to an extend prone to ink drying ... (not thermo-sub printers) ...

whether this starts to show after a week or after a day is likely depending on

the environment in which the printer operates (hot/cold ... dry/humid ... etc) ...

A good idea is normally not to switch the printer off entirely, instead, let it

sit in standby if not needed ... this way, the printer can go into a cleaning cylce

if it feels like it.

 

A thing I found helpful is to cover the printer with thin plastic foil  or something similar ...

this helps against dust.
