i. Resolution: This is measured in dots per inch (dpi). Laser printers have
resolutions that range from 600 to 2400 dpi. 600 dpi printers produce professional
black and white prints. 1200 dpi results in smoother edges and text that is crisper.
2400 dpi produce both professional and great quality text, along with great
graphics. Therefore, you will need to choose the best printer for your needs.
ii. Print speed: This is important especially if the printer will be shared over a
network. The range of printer speeds is from 12 to 45 pages per minute (ppm). The
speed is dependent on the processor of the printer, which is rated in megahertz
(MHz). The higher the megahertz rate, the faster a printer will function. Laser
printers have processors that range from 100-400 MHz.
iii. First page out: A laser printer can take 5 to 30 seconds to start printing. This
time lapse is known as the first-page-out time (FPOT). This is not inclusive of the
time to print the pages.
iv. Memory size: Laser printers have their own memory that can be shared over a
network. The amount of memory also determines the speed at which the printer will
work. The larger the size of memory, which is measured in megabytes, the faster the
printer will process multiple documents. The sizes range from 2-128 MB. A small
business of around 15 people would function well with 12-16 MB of memory for
small or short documents such as emails. If there are large documents such as
spreadsheets, a 64 MB printer would suffice.
v. Duplexing: Printer with this feature can print two-sided documents. This will help
cut down on costs for office paper. It’s an eco-friendly feature.
Laser printers therefore present better advantages compared to other types of
printers. They are the preferred choice for most business premises. With all the
features available, it’s hard to regret buying one. The best laser printers are
LaserJet printers.

Tattoo ink varieties
Tattoo inks are mostly made of combined pigments with carriers and their main
function is in tattooing. They can be found in varied colours and can be thinned or
even mixed together to provide different shades and colours as desired. They are
also found in both high quality and low quality.
Most of the inks used in doing tattoos are purchased when they have already been
made hence the common reference to them as pre-dispersed inks. They are either
water based or alcohol based. However, some of the tattoo artists prefer to mix
their own pigments and carriers to come up with their own tattoo inks. Thus, the
different tattoo artists use varied types of inks depending on their preferences.
Difficult removal
Majorly the tattoo inks that are used are permanent. Their removal is extremely
painful and difficult since its success level also depends on the kind of materials
