They may require arcane driver software that can be excruciatingly specific to a particular environment. Networked printers often assume different names, aliases, and labels at various nodes. Identifying printers and doing fault diagnosis can become a major system chore and often a headache. Networked printer problems can be due to the hardware, the software, or the network itself. Relief is available.
Organized control is the key.
Maintaining a printer usually involves mechanical support, such as replacing toner, ribbons, paper, and fixing an occasional jam. Managing and controlling networked printers involve all of the above plus support for installations, deletions, and renaming as necessary. Probably not very often in static environments where every user has one printer, all have the same model, all are in the same place, and all are installed at the same time. The reality is that printers can be added, removed, or moved about the network at any time at any location. In such an environment, it is often difficult to accurately measure the distribution of problems because so much is in flux.
