I don’t know if you would be the right person to ask about this but I’m having trouble with my printer. It tells me ( or told me) to replace ink cartridges - I did - but it’s still not printing correctly and it also won’t pick up the wireless signal. I may need a new printer but maybe not ...

With most printers there are a few things you can try. in the printer settings, there are usually a couple of different settings. You're looking for "restore network defaults" and/or "restore defaults". Anything close to that. Initiate those commands and it may bring the printer back to life. You can also try cleaning the print nozzles. There's a command for that in the software as well.

As far as the wireless issue goes, it can sometimes be the fault of the wireless network itself. You'd hate to buy a new printer just to find the same problem. The most common issue with printers not able to print wirelessly is that the wifi network has multiple instances of the same name. Or the network has been split into segments. ie: Sells Network 1, Sells Network 2, Sells Network Kitchen, Sells Network Basement. If the network router and repeaters are handling the home IP addresses incorrectly, you could have the printer on one network but your computer is on a different and they wouldn't be able to see each other.

Overall, the money you would use to pay me may be better suited to go toward a new printer. I feel that printers are usually for about 3-4 years then it's time to move on.
