A line matrix printer is a computer printer that is a compromise between a line printer and a dot matrix printer. A line matrix printer prints page-wide lines of dots, building up a line of text by printing lines of dots.
Line printers make use of continuous form paper which is usually perforated instead of individual cut sheets. Line printers print the full width of the page, one line of text at a time, instead of a print head moving back and forth across the page.
Line printers print a complete line at a time and have speeds in the range of 150 to 2500 lines per minute. The types of line printers are drum printers, band-printers, and chain printers.
Printronix line matrix printers are the most reliable, cost efficient and sustainable print technology. Lowest Cost per Page printing driven by hardware reliability and high yield low cost consumables. Media flexibility including multi-part, wide format, and continuous form media.
Line printers provide a substantially lower total cost of ownership versus dot matrix printers. Dot matrix printers employ expensive cartridge ribbons and print heads which are consumed in the printing process. In production environments consumable costs dominate the total cost of ownership.
Dot matrix printers are a lot like inkjet printers. They work by implementing a moving head that prints in a line by line motion. However, in contrast to inkjets, dot matrix printers employ an impact `head and ribbon` method of printing.
A printer printing lines on the page are normally caused by a blocked, dirty, or damaged print head. Blocked ink cartridge nozzles, or not removing protective seals correctly when you installed a new ink cartridge can also cause missing lines of print.
The line printer is a form of high speed impact printer. They can Print 300 to 3000 Lines per Minute. So that they are very fast. Large Computer system typically use Line Printer.
Line printer:

Typically, they can print in the range of 1,200 to 6,000 lines per minute. Drum printers, chain printers and band printers are line-in-time printers.

Line printers print an entire line of text before proceeding to another line. Most of the early line printers impact printer. Although line printers are primarily associated with unit recorders and the early days of digital computing, the technology is still in use today.
Direct thermal printing uses chemically treated, heat-sensitive media that blackens when it passes under the thermal printhead, while thermal transfer printing uses a heated ribbon to produce durable, long-lasting images on a wide variety of materials.
Unlike inkjet or dot matrix printers, thermal printers use a heated printhead to produce an image. This process creates images with high quality prints that can withstand greater abuse. There are two types of thermal printers: direct thermal and thermal transfer.
They work best on uncoated, relatively thin paper. Unlike laser or inkjet printers, however, dot matrix machines are appropriate for use with multiple-part forms, such as shipping paperwork and invoices. Due to their impact-based printing functions, they can print on all the parts of a single form in just one pass.
Modern Line Printers

They`re designed for low energy usage and utilize modern, long-lasting ribbons and inks for better print quality and longer consumables life.

Thermal transfer printers work by using a heated printhead that applies that heat to a ribbon that has a wax or resin coating, depending on the type of media. The heat from the printhead melts the wax or resin and transfers it from the ribbon and onto the media.
