Query: Good price, compact, quiet, but WARNING

Printer is an excellent price; it's compact, quiet, fast. However, buyer beware. What you're saving in upfront printer cost, you will make up quickly in ink. I'ts not that the ink cartridges are so expensive; it's that they don't last long. I've had this printer less than 1 month and am on my 3rd ink cartridge. I contacted HP tech and was told the HP 21 black cartridge average is 150 pages. Ink cartridges for my previous printer, Epson Color Stylus 600, were more expensive, but one lasted for 3-4 months; I haven't changed my printing output! The printer is nice, but if I had known the $$$$ of keeping ink in the printer would be so expensive, I wouldn't have bought it. So I give the printer 1 star to call attention to prospective buyers who might want to print more than a few pages every day.
