Network printers are not directly connected to a controller (usually a computer) but rather a print server, which exists as an accessible entity on the [[local area network]]. In some cases, the print server is an entirely separate server computer, through which all print jobs are managed. However, sometimes (especially in smaller installations) the printer uses an internal print server. Either way, when something is to be printed, the requesting device connects to the print server through the intranet (or sometimes internet) and delivers the print job. The print server then has the printer complete the task.<br />

Network printers are commonly used for frequent and high-volume printing, so they often use the Lasterjet method, which is fast and inexpensive. Laserjet printers are at least somewhat larger than most other printers. To provide the speed and functionality required, they are often towers which stand three to four feet tall.

===Plotter===
Plotter printers are used to produce images, usually on large sheets of paper. As plotter technology evolves, theses printers become faster, but they still generally take some time to complete their tasks. Since they are slower than most other modern printers, they are generally not used for regular-sized printing tasks.
====Flatbed====
Flatbed plotters have a tray, in which the paper (or other medium) is held stationary. The plotter uses a pair of pens (hollow fiber rods, sharpened at the end) which move vertically and horizontally across the paper, plotting out the final image. These printers are sizable, since they must be larger than their product.<ref name="techwalla.com">https://www.techwalla.com/articles/plotters-their-types</ref>
====Drum====
Drum plotters reduced the required size of this technology, which using the same basic method. Paper is attached to a large drum using a pin feed attachment. The plotter then runs pens vertically across the paper, and the paper itself is moved horizontally by rotating the drum when needed.<ref name="techwalla.com">https://www.techwalla.com/articles/plotters-their-types</ref>
====Electrostatic====

====Inkjet====
One of the newest and probably the most popular kinds of plotter uses the inkjet printing method. Liquid ink is delivered to the paper as droplets using the inkjet method

In general, these printers are very slow in comparison to 2D printers, but the technology is still evolving and improving significantly.<br />
Depending on the purpose and design of the 3D printer, it can use a wide variety of materials. The material is sold as filament sized at either 1.75mm or 3mm, which is fed into the nozzle, melted, and released as needed. These include:

====Support materials====
These are materials which are needed during printing to support parts of the product, during construction, but must be removed when the job is complete. These are printed to fill the space, then dissolved later, leaving only the intended product, with the intended voids.

===Thermal===
Thermal printers do not use any ink or toner. Rater, they use direct-thermal paper, which turns black in response to heat. These printers are limited to black printing only, and the final product can be destroyed sunlight, hot surfaces, or friction. However, they are inexpensive and convenient for a number of purposes, including shopping receipt printing and label production.

====Care and maintenance====
Since no ink is used, thermal printers tend to stay fairly clean. However, paper fragments and dust can still build up, so these should be cleaned from time to time. Compressed air and/or a damp cloth can be used to clean it manually. Some printers can also be cleaned by feeding through a cleaning card.
