UPS traces its history to 1907, when the American Messenger Company was started in Seattle by 19-year-old James E. Casey and another teenager, Claude Ryan. At this time, the founders decided to concentrate on delivery of packages from stores and therefore changed the company name to Merchants Parcel Delivery.
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
Offline UPS are systems where the load is fed directly from the raw mains during normal operations, rather than the inverter outputs, to the extent that power storage components such as chargers, inverters and batteries are offline as the load is concerned.
A switched-mode power supply (SMPS) is an electronic circuit that converts power using switching devices that are turned on and off at high frequencies, and storage components such as inductors or capacitors to supply power when the switching device is in its non-conduction state.

What is the Difference Between UPS and USPS. It is very easy to confuse UPS and USPS because of their acronyms, but they are two different companies. USPS, also known as the postal service or US Mail, offers domestic mail delivery services. It is funded by its delivery services and the sale of postage stamps.
If You Are Shipping Items Under 2 Pounds… USPS will always be cheaper than FedEx or UPS hands down. However as the weight creeps closer to 2 pounds, USPS pretty much reaches pricing parity with UPS and FedEx Ground. USPS really shines when your package weighs less than 13 oz and can be mailed via First Class mail.
For packages shipped on a Monday, USPS Priority Mail (1.79 days on average) delivered packages almost one full day faster than UPS Ground (2.75 days on average), and about a half day faster than FedEx Home Delivery (2.21 days on average).
For short distances, both FedEx and UPS can ship a 5-lb. ground package faster than USPS, and the delivery days are guaranteed. Another benefit to UPS and FedEx is that they can ship packages that weigh up to 150-lbs. The weight limit for USPS is 70-lbs.
Yes, but only if you are returning a package with a label stating at the top that packages may be given to UPS or the United States Postal Service® (USPS). The label indicates that your shipment was made through the UPS Returns® Flexible Access service.
The USPS is often mistaken for a government-owned corporation (e.g., Amtrak) because it operates much like a business. It is, however, an "establishment of the executive branch of the Government of the United States", (39 U.S.C. § 201) as it is controlled by Presidential appointees and the Postmaster General.
Fedex and UPS are the largest global courier delivery services; FedEx has a net income of about $2 billion on revenues of $42 billion while UPS is larger, with a net income of about $3 billion and revenues of $53 billion.
They make good money. On average, drivers today are paid $30 an hour, according to Glassdoor. That's double the amount they made in the mid '90s, according to NPR and the head of the Teamsters union, which represents UPS. At the end of his 38-year tenure, Dyer says he was making more than $75,000 a year.
