Devices do drift to an extent, inkjet printers included,.
But let's also not forget that they are supposed to be operating within
certain defined conditions, among them temperature, which is a concern in
the cold and hot seasons.
See the "Environmental Characteristics" listed for the Epson 7900, for
example:

If it's winter, and your inkjet is in a room at 45° F and 90% humidity, one
should expect that the device's behavior will be affected.
