How to Differentiate Between Laser Printers & Inkjet Printers

You require a new printer but you do not know whether to buy an inkjet or a laser printer, as you are not aware of the differences between the two. Each user or organisation is faced with the dilemma while buying a new printer. Most customers operate under strict budgetary constraints and it is only normal to consider initial purchase costs and space limitations. However, it is prudent to take into consideration the long-term operating costs associated with the particular printer.

The choice of printer will, largely, depend on your requirements. Inkjet printers are usually ideal for home users who have limited text and photo printing needs. Laser printers are better suited to larger office environments with high-volume and high-quality printing requirements.

The differences between a laser and an inkjet printer are generally categorised into a few broad segments, namely, cost (initial and maintenance), speed, quality, space and networking facilities. It is also essential to understand the technology behind the manufacturing of the laser toners and ink cartridges as this is a major contributing factor towards the cost.

Difference in Technology & Networking Facilities between Inkjet and Laser Printers

The technology used for inkjet cartridges is simpler and the parts are less expensive than the laser toners. The black inkjet cartridge has only black ink. The color inkjet printer contains two main ink cartridges, for black and other primary colors respectively. The primary colors are then divided into three compartments for cyan, magenta and yellow ink. The primary colors are consequently mixed to produce all other colors. The cartridge contains a reservoir which has compartments with metal plates and a number of tiny nozzles on the print head of the cartridge. The number of holes or nozzles depends on the resolution of the printer. It is usually 21 – 128 nozzles per color. The ink gets heated, when the current starts flowing through the metal plates, after the print command is given. The heat causes vapor bubbles to form inside the cartridge and make the ink swell up. The ink then flows out in droplets from the nozzles onto the paper in a few milliseconds. A vacuum is created (once the ink droplet flows out) which draws more ink into the nozzles ensuring a steady supply of droplets as required. This common technique is called Thermal Inkjet and the coinage of the name ‘BubbleJets’ by Canon has been due to the bubbling vapors.

The Laser toners use a more elaborate and complex technology. A powder called Toner is used by laser printers, fax machines and photocopiers to print text and images on laser and photo paper. Initially carbon powder was used but now manufacturers use disposable cartridges which can sometimes be refilled. For the laser toners, individual carbon particles are mixed in a polymer which melt in heat. This binds to the fibers in the paper. The laser printers consist of the printer toner and the drum. The positively charged toner gets attracted to the negatively charged drum. The toner is transferred to the paper by the drum. The toner contains special wax that melts and dries in milliseconds. When the toner is transferred, the fuser applies heat and pressure to make a durable image. The fuser system is made up of the hot-roll and the back-up roller.

The high-end laser printers generally come with networking facilities for you to connect to your computer network directly. This cuts down additional costs associated with networking, as is the case with ink printers. The ink printers cannot be linked to a network directly. Networking has to be via a computer, therefore more expensive.

The laser printers are larger in size than the inkjet printers. The latter is, therefore, space saving and ideal for the home and small office users.

Difference of Quality & Color between Laser and Inkjet Printers

Since Inkjet Printers spill out tiny droplets of ink to print, the resolution is lower than the laser printers. Laser Printers printer better quality text, as their resolution is higher. High resolution also helps the laser printers create precise fonts without fuzzy edges. However, the cost-effective inkjet printers are usually recommended for inexpensive color printing. These can print high quality text, large photo prints, graphics, banners and greeting cards at less than half the price of a color laser printer. Nevertheless, it should also be seen if the cost of ink and paper suits your maintenance budget. Laser printers are capable of producing good quality prints on all kinds of printing paper but the inkjet printers will require inkjet paper to produce good quality prints without any fuzzy edge brought about by ‘bleeding’.

Difference in Speed between Ink and Laser Printers

If laser printers lose out to their inkjet counterparts on account of price, they are way ahead when it comes to speed of printing. Users who need large volumes of printing also prefer the laser printers. Laser printers are more suited to general office use than the inkjets. The least expensive laser printer can print around 10 to 15 pages per minute. The inkjets are usually rated on the speed of draft or quick printing mode, which is suitable only for proofreading purposes. The HP Deskjet 5650, which is a fast color inkjet printer, prints at a speed of 21 ppm Black, 15 ppm Color in the draft mode. However, the speed drops considerably when high quality black text is printed and it also takes longer to print a letter-sized quality photo.

Difference in Cost between Ink and Laser Printers

The most important factor governing the choice of a printer is – cost. The cost can have two sub-categories – initial cost and operating cost- – which finally becomes the deciding factors in a purchase of a consumer item. The inkjet printers have a low initial cost but a higher maintenance cost when compared to the high initial purchase cost and low operating cost of a laser printer. The price of a monochrome laser printer can range from $ 130 (e.g. Brother HL2040) to over $ 3,000 (e.g. HP Q3721A Laserjet 9050) and the price range of color laser printers can be from $ 350 (e.g. Samsung CLP 510) to over $ 6,000 (e.g. HP Q3717A Laserjet 5550hdn). Conversely, the cost of color inkjet printers can range from approximately $ 35 (e.g. HP 9067A Deskjet 3930) to $ 2,000 (e.g. HP C7791D Designjet 130NR). However, laser printers are a better option for long-term office use. They are designed to handle high volumes and have a higher capacity of ink or toner. The ink cartridges require to be replaced often if you print a considerable amount regularly. The toner cartridges, though more expensive than the ink cartridges, hardly need to be replaced. This lowers the total cost per page. The out put of laser printers is good even on cheap paper whereas inkjet printers require special inkjet paper for quality output and this also depends on the grade and type of paper being used.

Cheap recycled or third party ink or toner cartridges are readily available in the market, the use of which reduces the maintenance cost to a great extent. However, you have to be careful while buying these when producing high quality photos and also be sure that the use of these does not cancel your warranty. Since ink cartridges of some new inkjet printers contain computer chips, you may not be able to use recycled or third party cartridges for that particular printer.

Keeping the above factors in mind, it is advisable to calculate the total cost of ownership before purchasing a printer. The initial purchase cost of an inkjet printer may be low but the cost as consumables like paper and ink may exceed your budget. The slow speed and variable print quality of the inkjets are also deterrents. Laser printers are definitely a better buy when the requirements are that of high print quality, speed, high volume and low operating cost over a long period of use.

Working Of Laser Printers

Laser Printers are commonly used printers that are known for its rapid printing abilities. The other marked feature of a laser printer is the high quality text and graphics printing. It works basically on the principle of xerographic printing process. However, it is different from the analog photocopying machines in which the image produced is the result of direct scan of a laser beam on the photoreceptor of the printer.

Using a laser printer has a number of advantages over any other types of printers available. The speed of a laser printer varies from one model to another as it depends on a number of factors like the graphic intensity required in processing the job and others. The latest models of laser printers can print more than 200 single color pages in one minute, which is more than 12 thousand pages in an hour! The color laser printers are relatively slower, but even they can print at more than 100 pages per minute. The high speed laser printers are generally used for printing of mass mailings like utility or credit card bills etc.

The cost incurred in using the laser printing technology is dependent on more than one feature such as the cost of the toner, paper, once in a while replacement of the drum, and change required in other consumable parts of the printer like transfer assembly and the fuser assembly. Laser printers having drums made of soft plastic can be costlier in the long run than one can comprehend; its high overall cost becomes apparent only when the printer requires a drum replacement.

Another feature in the family of laser printers is the duplexing model. This allows printing on both sides of a paper without the need to remove the paper at all. This technology can cut paper cost directly into half and also lessen the filling volumes. Formerly, the duplexing technology was available only on the high-end laser printers. However, now they can be seen on a number of mid-range office laser printers. Although, the duplexing technology can reduce the printing speed to some extent as the paper path length increases.

The dot-matrix and inkjet printers take the incoming spooled data for the printer and directly print that on the paper making it a slow process which can stop as soon as the printer is waiting for more data. On the other hand, a laser printer cannot work this way, the reason being the large amount of data required to output to the printer in a continuous fashion. The printer cannot wait for data arrival and if that happens, there can be gaps and misalignment on the page.

To take care of the above problem, a printer buffer is used. The data is built up and kept in the large printer buffer that is generally present in the printer. This data bank is large enough to account for every single dot that can be printed on a page. However, this requirement of storing the dots in the memory before printing can begin has limited the printing capability of laser printers to small size like A4 or A3. Most laser printer cannot print long banners as there is no memory to hold that amount of data.

The printing takes place in seven steps. A Raster Image Processor scans the entire page line by line and stores a bitmap of the page in the raster memory. The drum is then charged negatively and the bitmap is written on the photosensitive drum using a laser beam whose functionality is dependent on the bitmap image. The charged toner particles are charged negatively and wherever the laser has not discharged the drum, the charges will repel and printing won`t take place, hence creating the required print out. The toner contains a plastic powder that is attracted to the parts where the laser beam hit and in the end the plastic powder is fused at 200 degree Celsius to bond the ink with the paper.

Should I Buy an Inkjet or a Laser Printer?

In the world of printing, there are essentially two kinds of printers– laser printers and inkjet printers. Really, there are more, such as impact and photo printers, but most consumers in the home choose between these two So, if you are looking for a printer to use around the home, then keep reading. From now, I will tell you about the disadvantages and advantages of these.

The Lasers: Advantages

Laser printers print fast, are precise, and have greater print quality than inkjets. In this case, you really are getting what you pay for. A laser printer truly is just a better printer. Therefore, it is more expensive than an inkjet, but I will talk about this in the “cons” section. While the price of the machine may be higher than an inkjet, the laser toner is cheaper and lasts a long time. Most offices use lasers because they don’t have to replace the toner a lot. In the beginning, laser printers were very pricey. Nowadays, however, they are reasonably priced and affordable for home use.

The Inkjets: Advantages

Inkjets are not only cheaper than laser printers but they are pretty reliable as well. For example, I was in the market for a reasonable printer a few weeks ago. If you are just strictly looking for a cheap one, then buy in inkjet. Today’s inkjet printers usually are of good value.

The Lasers: Disadvantages

These can take up more space than an inkjet. So, if your office space is limited, it may be difficult to get one of these. Some cost a pretty penny. A good one could cost over one hundred dollars.

The Inkjets: Disadvantages

Most inkjets simply do not last as long as laser printers. Also, of course inkjets are cheaper than laser printers. But sometimes their print jobs are not as clear as lasers’ are. In other words, sometimes inkjets can leave ink spots on the paper. Another disadvantage is that while the printer itself is cheaper than its laser counterpart, the ink cartridges can be expensive. And also, the cartridges on the inkjet need to be changed more frequently than for the laser printer.

So it’s kind of like buying a cheap razor with expensive blades, or an expensive razor with more durable blades, if that makes sense.

Conclusion: Which One?

If price is your only concern, go with the inkjet. Just realize that the price of the print cartridges also adds up, because you need to replace them fairly often. I recommend buying the inkjet if you are concerned about space in the home. An inkjet truly gets the job done. In fact, I currently use an inkjet.

Offices usually use the better and more expensive ones. If the printer is used a lot, then it is probably a better value to buy a laser printer because that thing is a workhorse. If print-job quality is your concern, go for the laser.

There you have it. Thanks for reading!
