Description

Cloud printing system

The present invention relates to a printing system. Specifically, the present invention relates to a cloud printing system, which transmits the user's purchase content via cloud services to the store's printer for printing in real time.

With the advancement of technology, the ordering service of catering has been gradually derived from manual handwritten forms and converted to a point of sale (POS) operation and a stand-alone method. Its main function is to manage and count products. Sales, inventory, and recording of customer purchase behavior (for example, which type of merchandise they prefer to buy), and this application is not limited to the catering industry, retail and hotel industries, etc. have also been widely used. The point of sale (POS) information system with a stand-alone operation method is that the staff operate the point of sale information system (Point of sale) set up in the store on site, click and confirm the goods that the buyer wants to buy, Send the purchase message to the single machine for printing.

Today, the most common way of issuing orders is still the use of point of sale (POS) with a single machine. The point of sale information system is a physical POS machine, and the physical POS machine is often a machine or tablet. Then use the POS machine to transmit the customer's demand to the single machine and print it out. Of course, although this method of operation is convenient, it limits the scope of services. Taking the catering industry as an example, customers need to arrive at a restaurant to order food first, and waiters then operate the POS machine and the stand-alone machine according to the content of the order. It may take a while to get the meal. If the meal is crowded, the time required to wait for the meal will be longer, which will seriously affect the restaurant's table turnover rate and delivery speed.

On the other hand, taking the retail industry as an example, since the retail industry also often has physical stores (for example, stores), and physical stores have a fixed weekly/monthly purchase volume, if the number of people who need to buy is greater than the purchase volume, it will happen The shortage of goods caused the physical stores to issue orders on site, but they were unable to respond to demand and control costs immediately.

It can be seen from the above that the existing point of sale (POS) and single machine are easy to operate, but they cannot respond to a large number of orders immediately or make preparations in advance. Therefore, There is an urgent need to further develop a new printing system so that related industries such as the catering industry, retail industry and hotel industry can print orders through the printing system in real time, prepare in advance according to the order, and appropriately control costs to avoid unnecessary waste.

In order to solve the above-mentioned problems, the present invention provides a fast and convenient cloud printing system. One purpose of the present invention is to solve the problem that the prior art cannot allow the store to deal with a large number of orders or prepare in advance, and allow users (for example, customers or buyers) ) The system of the present invention can be used to make remote or cross-border orders and issue orders to stores (for example, restaurants, shops, etc.), and the store’s printer (for example, a single machine) will immediately send orders after receiving the contents of the order. The aforementioned purchase order is automatically printed out to remind the store to prepare in advance based on the content of the purchase order, and to allow the store to evaluate the required preparation amount in advance. On the other hand, when there is a large number of orders, the system sorts the order according to the time of each order and transmits it to the store’s printer for automatic printing. The store can then make products according to the order of the order.

Another purpose of the system of the present invention is to allow users and stores to operate easily. In addition to providing users with a new channel to instantly remind the store of new orders, the store can be more efficient and prepare products early after receiving the order. For example, when the store is given sufficient time to complete the preparation of the product before the customer arrives at the store, the customer can pick up the goods after arriving at the store by performing the checkout action, or make the payment at the same time as the order and directly after arriving at the store. To pick up the goods, there is no need to spend too much time waiting at the location of the store.

In addition, in order to allow users to conveniently use the system and select the products they want to order, when the user wants to enter the URL of the product catalog page into the browser, he can use one-dimensional barcode (such as barcode) and two-dimensional barcode ( For example, QR code) or picture (for example, photo) scanning method enters the URL into the browser.
