Hello,
The suggestion that Robert posted looks promising since JST housings are very commonly used for this purpose. Additional information such as the model number of the printer (there might be repair info), the wire gauge being used, and the pitch of the connector might be helpful. Here is a guide to connectors that includes the reference to “pitch” [ Terminology and Specifications of Headers/Pinheaders ]. It’s simply the distance between the center of each contact.
In a worst case scenario, you may try replacing connectors on both ends of the cable with a new type. That works best if everything is cable/wire mounted. It’s not as easy if you’re taking out a through-hole mounted part inside a device.
