No.A line printer uses characters.A laser printer uses pixels.More informationA laser printer uses a revolving charged glass cylinder. The laser can discharge the glass at points where no ink is wanted, causing the no toner to stick onto the surface of the cylinder at those points.Then the paper is pressed against the cylinder as it revolves, transferring the toner from the cylinder to the paper.The paper is then passed over a heater to melt and fuse the toner to the paper.A line printer is also known as a chain printer where the entire character font set is built up in metal type, with one character mounted on each link of the chain. The faces of the metal characters are wetted by moving across an ink pad.Each character position on the line has a hammer. When the right character is in the proper position, the hammer fires and then the paper gets pressed against the inked typeface to get an imprint.
A laser printer uses a dry toner powder in a sealed cartridge.
