Product: HP Laserjet 4000n with JetDirect
Operating System: Microsoft Windows 10 (32-bit)

Hello, I have an older but very reliable LJ4000dn which is connected to my home network via an Ethernet cable and JetDirect card. I wanted to place the printer somewhere without network wiring, and as I have an old Wireless Printing Upgrade Kit lying around, I was wondering whether I could simply buy a USB to Ethernet adapter and connect the wireless receiver to the printer that way.

 

Something tells me it's not quite that simple, but with my limited networking comprehension I can't figure out where my mistake is...

 

Thanks!

I am not quite sure what the wireless upgrade kit you have is. The challenge of course is that the 4000 does not have any usb ports. If you can source one of these

It is older and slower, there might be other devices out there but a quick search showed not many parallel based.

 

This is another option

Thank you Repairatrooper!

 

It's an older HP SDCAB-0603, with a standard USB printer output.

 

The two options you have listed are rare as hen's teeth and accordingly expensive, at least in Europe. They would not be worth it.

 

My question is: can an ethernet to USB converter (which must surely be bidirectional) translate the protocols? Presumably, the server receives TCP/IP packets destined for the DirectJet IP address via wifi and translates them directly to printer commands on the USB port, so you can't just change it back to appropriate TCP/IP packets with an adapter.

 

Is my reasoning correct?

Had to look that up. Maybe I am missing something, but the 4000 series never shipped with a USB port so I am not clear on how you plan to convert that USB A connector to your 4000, or did you plan to use a USB to parallel cable? I have never tried and do not know anyone that has. You can likely find a usb-parallel cable at a thrift store (I think term on your side of the pond is charity shop) for very little cash and try it.  Would be real curious if it actually works.

Thank you. The printer has a JetDirect card installed, and is shared on the network via a TCP/IP port. The idea was to use a USB to RJ45 (Ethernet) adapter between the wireless USB receiver and the printer.
