I have HP 2050a (J510a) and When I prints something it prints good for some time...But after some lines there is a change in sound and there are white spaces in between of printing page....whether it is text or picture....It is happening while every time whether I print from pc or directly copy from printer..I just had bought my cartiage and I am using Windows 7 Ultimate.
I am attaching a picture of scanned document which was earlier printed from my printer.
