"JS" through the JS implementation of the supermarket ticket printing function--activex control

• In response to customer demand = =, to the web-side to achieve the function of printing small tickets
• First, a printed small ticket (the total is obviously wrong, because there is the ability to modify the order, please ignore)

　　

• What is the way to achieve it: I think there are three kinds of it

1. Using a third-party browser control (this seems more convenient, my teacher also recommended me) to recommend a LODOP print control

2. Use CSS to write the template, and then directly with the page printing method (it should be so)

(The above two have not tried, these two days to try again)

3. Use Microsoft's own ActiveX control (ActiveX controls can implement calls to local files and other operations (previously tried to call CMD, implementation of Shutdown-s-T, on the Web control computer timer shutdown))

Of course, the disadvantage of this approach is also obvious: limited operating system-because it is Microsoft's things can only be under Windows, browser-because ActiveX can only be in IE browser. So the limitations are relatively large

• Implementation process:

1. Edit "Word Small ticket template", to use the word "bookmark" this tool (through the "bookmark" positioning, JS can manipulate word in "bookmarks" the location specified by the changes, write content)

2. Open, assign, print to the Word template in JS

• One, edit "word Small ticket template"

1. Take word2007 for example, first arrange the approximate style

　　　　　　

2. Mark positioning with "bookmarks"

Select the text area you want to bookmark-click "Bookmark"-fill in the book signature-click "Add"-"locate" to see the location of this bookmark

• Second, JS

Directly on the source code bar:

<type= "button"  value= "Toprinter"  onclick= " Viewtoword (); " />  

1 functionViewtoword () {2         //Current Time3         varTime ;4         varToday =NewDate ();5Time =today.tolocalestring ();6         7         Try {  8             //Create a ActiveXObject object9Wdapp =NewActiveXObject ("Word.Application"); Ten         }   One         Catch(e) { AConsole.log ("Unable to invoke Office Object!

Size = 8;//Adjust font size -InsertAfter ("blog Park" +i);//What's inserted the             } +             //second column A              with(Mytable.cell (i,2). Range) { theFont.

Range) { -Font. Size = 8; theInsertAfter ("Priceless"); -paragraphformat.alignment=2;Wuyi             } the         } -Wddoc.saveas ("F:\\printertemp_cnblogs.doc");//Save temporary file word WuWddoc.

• Attention:

The first thing to do is to adjust the Internet options for IE browser-the custom level (under "ActiveX Controls and plugins" on the right, which can be enabled)

　　　　

"Printer offline work" is generally USB is not plugged in, switch the socket, restart the printer can
