Some HP inkjet printers use cartridges that expire 12 or 24 months after their warranty ends, or 18 or 30 months after being installed in your printer. Some of these printers will refuse to print until you've replace an expired cartridge.
Legend of the shamrock. St Patrick. The Irish shamrock symbol is closely associated with St Patrick, the patron saint of Ireland. St Patrick is believed to have been from Scotland or Wales. Irish raiders captured and enslaved him at the end of 4th Century. He spent six years in slavery, probably in the West of Ireland.
Because of its theological significance, the shamrock has become a national symbol of Ireland as an expression of the Irishâs faith in the Trinity. Thus, although one often sees four-leaf clovers as symbols of Ireland in advertisements, it is the three-lobe shamrock which is the proper symbol.
