Why does my text not print? - c#

Realizing that I should be using Line Print mode (as opposed to label mode) for sending CPCL to the Zebra QL 220 belt printer, I'm in the process of refactoring my working code (Why does everything print on the same line, even though I'm adding crlfs?) to this:
serialPort.Write("! 0 200 200 210 1\r\n");
serialPort.Write(string.Format("! U1 setvar {0} {1}", "device.languages", "line_print"));
serialPort.Write("Hallo die Welt\r\n\r\n"); //Bonjour le Monde --- Hola el Mundo --- Hallo die Welt
serialPort.Write("BARCODE-TEXT 7 0 5\r\n");
serialPort.Write(string.Format("BARCODE 128 1 1 50 150 130 {0}\r\n\r\n", barcode));
serialPort.Write("POSTFEED 120\r\n"); // empirical observation shows 120 is about the right amount of extra tape to expel after printing
serialPort.Write("PRINT\r\n");
This prints the barcode and its human-readable number beneath it (the value in "barcode"),but the text "Hallo die Welt" is not printed. Why not? Do I need a call to Print after each line, or...???
UPDATE
It still prints the barcode only (not "Hallo die Welt") with this code:
serialPort.Write("! 0 200 200 210 1\r\n");
serialPort.Write("! U1 SETLP 7 0 24\r\n");
serialPort.Write("Hallo die Welt\r\n\r\n");
serialPort.Write("BARCODE-TEXT 7 0 5\r\n");
serialPort.Write(string.Format("BARCODE 128 1 1 50 150 130 {0}\r\n\r\n", barcode));
serialPort.Write("POSTFEED 120\r\n");
serialPort.Write("PRINT\r\n");
UPDATE 2
This works (label mode):
serialPort.Write("! 0 200 200 210 1\r\n");
serialPort.Write("TEXT 4 0 30 40 Hallo die Welt\r\n\r\n"); //Bonjour le Monde --- Hola el Mundo --- Hallo die Welt
serialPort.Write("BARCODE-TEXT 7 0 5\r\n");
serialPort.Write(string.Format("BARCODE 128 1 1 50 150 130 {0}\r\n\r\n", barcode));
serialPort.Write("POSTFEED 120\r\n");
serialPort.Write("PRINT\r\n");
It prints:
~~~~~~~~~~~~~~~~~~~~~~~
Hallo die Welt
<barcode as a barcode>
<barcode as a number>
~~~~~~~~~~~~~~~~~~~~~~~
...but this doesn't work (line print mode):
serialPort.Write(string.Format("! U1 setvar {0} {1}", "device.languages", "line_print"));
serialPort.Write("! U1 SETLP 7 0 24\r\n");
serialPort.Write("Hallo die Welt\r\n\r\n");
serialPort.Write("! U1 BARCODE-TEXT 7 0 5\r\n");
serialPort.Write(string.Format("! U1 BARCODE 128 1 1 50 150 130 {0}\r\n\r\n", barcode));
serialPort.Write("! U1 SETLP 5 2 46");
serialPort.Write(barcode);
serialPort.Write("! U1 PRINT\r\n");
The problem is, I need to use Line Print mode.


You also need a \r\n after every SGD command (your setvar in this case)
It should be
! U1
setvar "device.languages" "line_print"\r\n
You also need to put the double quotes around the 2 parameters of the SETVAR command.
UPDATE:
oh, btw, just because the printer is in line_print mode, doesn't mean that it doesn't understand CPCL code. So the code above in your example is CPCL code, not just line print. If you put TEXT in front, it should work

TwinCAT3 - Automation Interface - Display O/P on Jenkins console

Using Automation Interface I could able to build and initiate Activate Configuration in TwinCAT 3.1.4024.4.
If same project under normal run and Activate Configuration, Messages and errors are displayed in the output console of VS2013.
In Automation Interface, Using ErrorItems errors = dte.ToolWindows.ErrorList.ErrorItems; I could only read and display message 1 to 10.
Other Messages has different format TwinCAT System (10000) or PlcTask (350):
Is this will not be captured by dte.ToolWindows.ErrorList.ErrorItems; ?
In the output console of VS2013 there are two options: Show output from build and Show output from twinCAT.
In Automation Interface,I think, i could only read messages from build and no Messages from TwinCAT
Is there any way to read TwinCAT messages Also?
VS2013 console output:

I see that you are using TcUnit.
The problem is that you’re not waiting for TcUnit to finish before you are collecting your ErrorItems. You are only collecting the error items after doing the ActivateConfiguration() and StartRestartTwincat() (that’s why you only get the first 10). You need to wait for TcUnit to finish.
Wrap the running of TcUnit in a while-loop, and ask TcUnit for the results. Once all results are returned (which is done when you have all prints done), you can then use your ErrorItems. So basically, collect the ErrorItems in a while-true loop (but make sure to use a sleep every second or so), and once you have all the results from TcUnit (in other words, the lines ==========TESTS FINISHED RUNNING========== and everything that follows), you can print all error items (or parse them, or do whatever you want with them).
Good luck!

Thank you #Jakob
Your suggestion helped to solve this issue.
After restart, 10 seconds of wait and after each read, 5 seconds of sleep.
sysMan.ActivateConfiguration();
sysMan.StartRestartTwinCAT();
System.Threading.Thread.Sleep(10000);
ErrorItems ACErrors = dte.ToolWindows.ErrorList.ErrorItems;
ErrorItem ACErrorsItems;
int j = 1;
do
{
System.Threading.Thread.Sleep(5000);
ACErrorsItems = ACErrors.Item(j);
j++;
if (ACErrorsItems.ErrorLevel != vsBuildErrorLevel.vsBuildErrorLevelLow)
{
Console.WriteLine("Description: " + ACErrorsItems.Description);
}
} while (!ACErrorsItems.Description.Contains("| 'PlcTask' (350): | ================"));

Independent of the VS ErrorList, another way to access the output window, e. g. to catch the build information:
// access output window in VS
EnvDTE.OutputWindow outWin = ((DTE2)dte).ToolWindows.OutputWindow;
try
{
// get specific output window of the collection
EnvDTE.OutputWindowPane Buildpane = outWin.OutputWindowPanes.Item("Build");
// get text document of the selected pane
EnvDTE.TextDocument BuildtextDoc = Buildpane.TextDocument;
// select all text in the output window
EnvDTE.EditPoint BuildeditPoint = BuildtextDoc.StartPoint.CreateEditPoint();
string Buildtext = BuildeditPoint.GetText(BuildtextDoc.EndPoint);
Console.WriteLine(Buildtext);
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}

Can Photoshop Caption Digest metadata be added by another program?

FFmpeg missed packets (from time to time) while copying RTP stream to file

I have and RTP video broadcast stream (using NOVUS – H.264 / MPEG-4 HD/SD Broadcast Encoder). And I have a Windows Server 2012 (Intel Xeon E5-2690, 128Gb RAM) with service which is recording this stream to file (using lastest FFmpeg, calling it as external process). Every 2-5 minutes recording stops and starts again to a new file.
From time to time there are significant (and not) lags in video. At most these lags are at the beginning file, sometimes in the center/end. Regarding log there are missed packets.
It could be network problems, but:
I ran manually from console in parallel another instance of ffmpeg and started to record the same broadcast stream with segmentation by time. And in this case recording is very good (missed packets 1..5 very very rarely), no lags. At moments, when the first ffmpeg records the second ffmpeg has no problems.
What could be the reason of this behavior? Two ffmpeg instances run in parallel and read the same udp input, but the first misses packets when the second feels good. No memory problems, no hdd problems, no CPU overload. I also tried to set highest priority of the first ffmpeg process, but it didn't help. The only difference between them I see is that first ffmpeg is run from service, and the second is run from from local administrator. To be honest, I used vlc as recorder before, but it had the same problems too... And I can surely say that video stream is ok, because it is played in VLC player 24h/day on another PC without lags...
That is how I run ffmpeg from windows service (C#):
_process = new Process();
var startInfo = new ProcessStartInfo(#"ffmpeg\ffmpeg.exe");
startInfo.UseShellExecute = false;
startInfo.RedirectStandardInput = true;
startInfo.Arguments = "-loglevel debug -y -ss 1 -i \"" + _url + "\" -vcodec copy -y -an \"" + _outputFileName + "\"";
startInfo.CreateNoWindow = true;
Command to record video automatically from windows service:
ffmpeg.exe -loglevel debug -y -ss 1 -i "rtp://225.1.1.1:1024" -vcodec copy -y -an "Session-021221.ts"
Command to record video manually.
D:\ffmpeg\ffmpeg -i "rtp://225.1.1.1:1024" -vcodec copy -an -f segment -strftime 1 -segment_time 300 "novus-%Y-%m-%d_%H-%M-%S.ts"
This is part of the log of one of the broken recordings (some other full logs are attached):

I can quite easily generate a 3D scatter plot using this command in gnuplot:
splot "C:/path/to/points.dat" with points
What I'm really after is a way to "fill in the gaps" and create a surface. The ultimate goal is to use data like the points shown above to generate an RF map for a given WiFi access point. The resulting map would be used to calculate the possible locations of a device, given its RSSI (received signal strength indicator).
(Several APs and their associated RF maps will be used, however I don't think the specifics are relevant to this question.)
What would be the best way to interpolate the z-values (RSSI in dBm, in this case) for the remaining points?
EDIT :
I seem to have made some progress. Using set dgrid3d 50,100 splines before the splot command seems to generate more or less what I'm looking for. So the next question is: how can I replicate this kind of function in code (C#, ideally)?
