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.
But bear in mind that USB-enabled printers require specific cables to make the connection, and that not just any USB cable will do. The standard type of printer cable in use with todayâs printers is called an AB cable. On one end of the cable, you have a USB-A plug. This is the familiar flat, rectangular end that fits into your computerâs USB port. The other end of the AB cable contains a USB-B plug, which is smaller and square. This is the end that plugs into the printerâs USB port.
