I am using hp deskjet 1050 all in one printer from last 3 years. Till now I didnot get any problem easy to use very convenint.for using 3 years I didnot change the cartiage I just refill it and use it.best printing quality it is also very compact it takes small place to keep.it comes with two colour i.e. black and white. I have black.it carries 3 button in top which is for black and white printing, colour printing and if some how any paper blocked inside the printer then 3 button cancel will clear the blockage and the paper comes out easily.it carries a connectivity port in back and one switch for on and off. It carries 2 removeable cartiage so we can refill and use it.i will recommend this printer. value for money.
