I'm having an issue with my printer (HP PS C4780), when printing in black the print is barely visible and very streaky. I've tried resetting the printer, replacing the cartridges, cleaning the...

Did you replace the cartridge with brand new one? or refilled one?

I'm assuming that your cartridge head may be clogged by ink.....

If you have a refill tool, you can do some stuctioning job....if you don't have one..

Pure some water in paper cup (prefre warm watter) and then leave your cartridge for 20 min to resolve the clogging probelm

And take out your cartridge from water.... and wipe out the head.... and put them back to printer.

If you would like to save money, try refill kit by "ROADINK".
Not only they are easy, but also the printing quality is good.
For your better understanding pls check out my youtube video.
And will see how easy ink refill can be done.

You don't need a CD, a user manual will be available at the manufacturers website showing how to do a factory reset and enter your own password and SSID. (I could've told you how if you'd named the make /model of router.)
