I have an officejet 4500 wireless G510n. It was working fine until I installed a new ink cartriage. The printer says it is printing but never prints.
I have tried the diagnostic tools, it says unknown error (48) on device status. I have restarted, uninstalled and re-installed, updated drivers, power restart, everything I can find on the troubleshooting. The diagnostic tool told me to come here to try to get help.
