Have seen that people recommend getting a cheap laser printer, but wondering if there's a cheaper inkjet solution available that's reliable in a light use scenario.

Black and white printing only, don't need colour.
It would be used a few times a week I think.

I'll be supporting this so if there's a printer that can be refilled, I can handle syringes and refilling etc.

Having spent hours troubleshooting some printers with shop-refilled cartridges recently would prefer a printer without the sensors that detect refilled cartridges if possible!
