Answer:

In the process of acquiring good peripheral devices in order to attain the needs of your business, you need to consider various factors before you make the decision to invest; nevertheless, this should not be difficult if you know the kind of services that you want (Ariav, Lindabury & Origlio, 2018). Ariav et, al. (2018) states that there is no such kind of a thing as one-size-fits-all the solution. Having a little time to learn about the functionalities offered by a peripheral device, along with the requirement that you have for the peripheral device will help you in making the decisions about the kind of device that best fits your business requirements. in our case, Dwayne the owner of Dwayne’s Digital Photography Services has various peripheral device requirements. For instance, Dwayne takes pictures using high end digital cameras; he prints business letters and invoices as well. Therefore, Dwayne needs a monitor for displaying his files before he prints them. Dwayne also needs hard drives so that he can be able to store data before transferring it between computers. Due to these requirements, I recommend the following list of peripheral devices for Dwayne to purchase.

Printer – Epson SureColor P800 Printer

Monitor – BenQ PD3200U review

Scanner – Canon CanoScan 9000F Mark II

Storage device – Western Digital 2TB Elements Portable External Hard Drive

According to Park et, al. (2014), BenQ PD3200U review has various characteristics that make me recommend it to Dwayne as a peripheral device. For instance, it is a 4K resolution large screen. This means that its resolution power is 3840 x 2160 pixels and therefore capable of handling both business and pleasure activities. Park et, al. (2018) also argues that with such kind of high resolution, this screen helps in avoiding squint at minuscule icons and small texts. BenQ is a brand that is trusted when it comes to monitors and also there are big things to be said when it comes to other displays such as BenQ EW3270ZL and BenQ EW2770OZ.When it comes to pricing and availability, the size of 4K is not going to be a budget proposal. Nevertheless, the price of monitor being $1,000 is reasonably priced.

Epson SureColor P800 printer on the other hand, is a printer that applies the use of Ultrachrome HD ink which is a new nine-color ink-set that produces a large color gamut enabling user to print photos that have various ranges of accurate colors and dense blacks. Also, Ultrachrome HD possesses light fastness that is more improved thus translating into long-lasting and durable prints. The printer also comes with a unit for roll papers that is optional. This means that photographers and artists now can print large formats on banners that are large. The SC-P800 can also be used in the production of a range of documents like synopses rendering, and presentation. The SC is consisted of three paths of papers, along with a new front-loading fine art paper which is made to switch between different media forms much easier. The printer makes use of 80 ml ink cartridges to make the printer ideal for large photo print.

Epson SureColor P800 printer uses both roll papers and individual sheets. Therefore, for Dwayne to get started on photo printing, I recommend him to purchase the Red River papers which are up to 17” in width appropriate for him. In addition, the Red River papers are better than the premium retail brands. For instance, we have the Ultra Satin 4.0 17x100 roll which costs $71.95. This roll will be good if Dwayne considers using it. On the other hand, Dwayne might choose to use individual sheets of papers and therefore I recommend Dwayne to use Marrutt Professional Photographic Papers which are quality and are used by the thousands of professionals across the globe. The cost of A4 papers is $16.12 for a box of 25 sheets of papers.

Many findings say that this printer uses cartridges and after some time they need to be replaced. When such a thing happens, I recommend Dwayne to use the Marrutt Refillable Cartridges for the Epson SureColor P800 which are reliable, and have continuous bulk ink delivery without having to do away with the expensive cartridges. The cost of these cartridges is $236.35, and they have the potential of giving service for a long period of time as long as the printer is working well. They even come with a one year warranty meaning they are capable of serving you for an extended period. The cartridges come in different colors therefore what you are required to do is refill the cartridges with the appropriate color when it is finished.

The price of cartridges might be expensive and therefore before you settle on a printer it advisable that you do some calculation on the cost of cartridges. Ink cost is calculated by dividing the cost of ink cartridges. For instance, the price of genuine cartridge for The Epson SureColor P800 black cartridges is $35.99 and its page yield is 480 pages. After some divisions are performed, the cost of one page is found to be 7 cents. Relatively, you can choose to purchase the real black Canon PGI-250XL cartridge for $9.99, which gives up a yield of 500 per page. The price of the page is 5 cents for Canon and it gives you a lot of ink at a low price. This is the reason why the price of the cartridge and the price ink yield are import factors to consider before you decide to purchase a cartridge.

Canon CanoScan 9000F Mark II is type of a scanner that is used by professional film, photo and document scanners. Therefore, I would recommend it for Dwayne. Their features are of the highest quality. For instance its scanning ability is of 9600x9600dpi for film and 4800x4800dpi for documents and photos. The printer has high printing speed of 7 seconds for A4 color at 300dpi. The film scanning speed is 18 seconds for 35mm negative at 1200dpi. It has an auto image correction feature. This feature and more others will be of great help to Dwayne in his work.
