The favorite solution of choice for Epson inkjet owners is a window 
cleaning product that contains ammonia such as Windex brand in the US.

With Epsons, the print head is part of the printer, not part of the ink 
cartridge.  So when Epsons get a clog, you either fix it or get a new 
printer.

Inkjet printers are not the best choice for printing only once per year; 
if you do this, think about running a test print once a month at least 
to keep the heads open.  Also, most printers need to be powered off by 
the power switch which causes them to move the print head onto either a 
pad or on some, they actually close a "door" over the nozzles.  Simply 
removing power (yanking the plug, etc.) won't perform this and the heads 
then may dry out creating a clog.
