printing - What's the best way to directly print to a printer, like POS printer, over the web? -

-

Is it possible to print from a web app to a network printer? Are there any POS or similar form factor printers that can be connected to the internet and printed directly (given that a port has been opened through a router)?

My ideal case would be a printer, on which I send XML and print it without the need for PC and therefore no driver.

One more thing that is good is to create an SSL connection on the printer, but this is not important.

Most thermal POS or labels can be connected to a printer manufacturer with an add-on network card from the printer is. The big brand names are Zebra and Intermax.

The interesting thing is that most of these printers have direct ASCII mode, so you just connect to a plain old TCP / IP connection and spit some formatting commands. ., Is written in a proprietary printer language which the manufacturer will give you. In the case of an intermediate, it is called the IPL (Intermediate Printer Language).

You have two options ... You can click on a button on the user, refresh one page, and on the server side, simply open printers and print a TCP / IP connection. It will also work for serial port printers and regular Windows printers. In fact, we have recently implemented it in a project. Your second option is to open a connection to the printer to write some client-side code, javascript or what-is, and the same printer spit the message. Warning: You might do this in security concerns because the browser can not take your page to the beginning of an outbound connection with a random IP address. If you are behind a corporate firewall and you can rely on doing some tweaking in the customer protection model, then it may be possible.

Personally, I prefer printing from server side instead of client side.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
