In the beginning we have only one HP Business printer. Since it is new, we face no problem with it until hubby's staff refilled the ink. Due to it we have to buy new printer head a few times. Since then, hubby informed his staff to wait for him to refill the ink. A very costly mistake indeed. =(
Now, besides the printer, our photostate machine can also prints. That save a lot of printing cost but it can only print in black and white.
