We currently have a HP Laserjet 4250, which keeps failing to print big jobs. It'll print smaller jobs, but only for a short period of time before it fails. In order to get it to work again, you have to restart it.

I think there might be something wrong with the memory on it, but I don't know that much about printers, so I have no idea where to start! Could anyone point me in the right direction please?

Thanks.
