I do have a colour printer, but the coloured inks are more expensive than the printer (go figure)
Inkjet ink has been a scam since its invention. The printers are presently sold as "loss leaders" simply as a mechinism to sell ink. When a three-in-one printer barely breaks $100, but replacement ink is $40-60, the economics get to be very obvious. The print heads are also hugely wastefull of ink, too. But, that gets "up" time, which consumers insist upon.
Sad truth is that color toner (sometimes called "laser") printers, even at three times the entry price are far cheaper to operate. (Replacement color toner cartridge runs about a c-note, but prints, reliably, about 6-7 times as many pages as inkjet.)
Downside for "us" is that far, far fewer decal films are compatible with color toner versus inkjet (with the codicil that the best decal tech is from dye sublimation printers--which are both the best color printers, and the priciest option around).
For persons not in Commonwealth nations a "biro" is a comoon pen, in the US, we'd probably call it a Pilot Point. Although, in common usage it often refers to a ballpoint, e.g. a "bic" pen.
The creatiity on this remains without parallel.
