I. Overview:

Common methods of report printing include:

1. Use activex to print but can only be used in IE, but Microsoft has abandoned the monopoly of IE,chrome, and the new version of EDGE uses the chrome open source kernel.

two。 Generate pdf printing but the efficiency and printing effect are limited. You batch print data to try, not tired you, generate a pdf, click to print once.

3. Use js to transfer data to the report server, compatible with a variety of browsers.

4. Android IOS custom printer printing, or using the printer interface to print.

Can so many prints be unified? This is the HttpPrinter we use now. Through Http communication, the printer server sets the template format and sends the data to the server.

2. Characteristics:

1. No plug-ins, just one sentence called js.

2. Drag and drop to complete the design. Thank you for the support of Ruilang report and the pride of the Chinese people.

3, powerful report function, no matter what report, cross, nested, or QR code, pictures, etc., are supported.

4. Printers: all printers are supported as long as they are available, needle printers, laser printers, receipt printers, card printers, etc., and printers can be specified when there are multiple printers

Support a variety of languages, java php js delphi python ios andriod, etc., languages that provide Http communication support.

3. Prerequisites for use:

1. Before printing, we need to design the printed report (we use Ruilang's website is the pride of http://www.rubylong.cn report developers)

2. The print data must be sent to the print server in Json format, and the data must meet the specified format (see below)
