Laser Printers

Regarding this printer type`s energy cost, a laser printer uses more power than an inkjet printer. Some commercial laser printer models use up to 1000 watts, with 300 to 500 watts being the average.

HP LaserJet Tank Printers have an internal toner-prefilled tank that you can print up to 5000 pages when you buy it. In the case of a small business printing approximately 500 pages a month, the HP LaserJet Tank Printer can print for 10 months without the need to replace toner or refill toner.
To calculate: Take the monthly volume or the prints/copies per month and the speed of the device. Determine how much time the printer or copier would actually be printing and how much time it would be on, standby, sleep, and off modes. Then multiply the hours per month for each mode by the power used by each mode.
An average ink-jet which is designed for home use will typically use 30 to 50 watts when it is printing, in standby mode most printers will draw around 3 to 5 watts of power. Commercial printers which are used in an office will draw 30 to 50 watts on standby and 300 to 500 watts when printing.
As a rule of thumb, to achieve photo quality print, you will need to use an image resolution of 300 pixels per inch. We write this as 300 DPI and means that in each inch of your print there will be 300 pixels.
Recommended monthly print volume is the number of printed pages per month within the stated range for optimum device performance based on factors including: The paper and toner supplies used.
As explained, laser toner cartridges deliver significantly higher page yields than ink cartridges and last much longer. Where most ink cartridges will print between 135 – 1000 pages, laser toners can print anywhere up to 10,000 pages each refill or replacement.
Laser printers are built to accommodate the demands of a workplace so they are engineered to print faster (between 15 to 100 pages per minute, or ppm), while inkjet printers print slower at about 16 ppm.
Laser printers can print much faster than inkjet printers can. Most are equipped with high-capacity paper trays, so they can print more pages at a given time. They`re also built to handle the printing of thousands of pages per month without succumbing to wear-and-tear.
But—and it`s a big but—lasers are not good for slicing through tank armor. All tanks have thick slabs of heavy steel, ceramic composite, and even depleted uranium armor welded to the front of the vehicle. It will take time—and sustained power—to burn through that armor on the battlefield.
Although laser printer cartridges are more expensive, laser printers have a significantly lower cost per page than inkjet printers, particularly if you`re looking to print a lot in black and white.
The largest burners typically pull around 2,500 watts when turned on to the highest setting. Medium-size burners pull, on average, between 1,500 and 1,800 watts on the high setting, while small or simmering burners pull an average of 1,200 watts.
Consider that a typical personal printer holds about 100 to 150 sheets of paper in a single tray, while a business printer will hold a minimum of 250 sheets.
If you run a smaller business that does less printing, you may well have a typical home / desktop printer. If so, you`re likely to see a home inkjet printer consume between 30W and 50W an hour, and a home laser printer use between 300W and 550W an hour. Both will use considerably less when left on standby.
2:3 is the most popular aspect ratio for printing. Print sizes that are a 2:3 aspect ratio and are popular with poster, canvas, and decal printing are 24 x 36 inches and 40 x 60 inches.

Get up to 5,000 pages or up to 2 years of pre-filled toner and save with the HP Toner Reload Kit.

Most laser printers today have a default resolution of 600 x 600 dpi, which is fine for everyday text printing. For sharper output when printing photographs or documents combining text, photos, and charts, a higher resolution, such as 1200 x 1200 dpi or 2400 x 600 dpi, is preferable.
On average, inkjet printers consume between 30-50 watts of electricity when in use, while in standby mode, they use 3 to 5 watts. It is recommended to turn off the printer when not in use or to use power-saving modes or automatic shut-off timers.
Let`s say, for example, you want to make a 5” x 7” print (sometimes erroneously referred to as 5 x 7 pixels). A good quality print will require a resolution of 900 x 1260 pixels. For a better-quality print, use 1200 x 1680 pixels. Finally, for the best quality, you should go with 1500 x 2100 pixels.
The best print speed for everyday prints (medium quality) is about 50–60 mm/s. However, users should note that some materials can be printed very quickly (e.g. PLA) while some require a slower rate to prevent warping or print failure (e.g. TPU).
power consumption 0 watts (off), 7 watts maximum (Powersave/standby), 285 watts maximum (printing).
As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.
On average, inkjet printers consume between 30-50 watts of electricity when in use, while in standby mode, they use 3 to 5 watts. It is recommended to turn off the printer when not in use or to use power-saving modes or automatic shut-off timers.

HP Laserjet 1320tn printing grey instead of black
ANSWER : Try this test. Put a page into the manual feeder and do that same test. When the end of the page is just about to enter the printer, open the lid. Take out the toner cartridge and pull back the shutter. Look at the image and see if it is black. The explanation is that there is high voltage going to both the toner cartridge and the charge transfer roller below it. If the image on the drum is black, then the fault is at the transfer roller not getting enough high voltage. The transfer roller pulls the image off of the drum and down onto the paper. It would not be a laser scanner problem as any issue with it would not result in an overall gray image, but combination of gray and black. It will probably turn out to be a bad HV power supply, which will need replacement. I’ve never seen this particular problem on this model.
