First of all, determine the extent of oxidation on the aluminum surface. If it is determined that the surface is in relatively good shape, i.e. light oxidation, then skip this step and move on to polishing with Flitz.
Q: how long can a usb printer cable be? I am trying to connect a HP laserjet 2840 to my iMac with a USB 2.0 cable that is 25ft long. The computer does not recongnize the printer or that it is connected when I plug them both in. The same 25ft cable works fine when connected to my other HP P1006 printer. The HP 2840 works fine when I use a shorter usb cable.

Then, connect the other end to an available port on the back of your wireless router. Not all routers support USB connections, but most routers have extra Ethernet ports to connect devices.Step 2.onnect one end of an Ethernet cable or USB cable to an available port on your printer.
