C Sharp :: Write Escape Sequence For Epson Printer
Sep 7, 2012
I want to send control codes for Epson printer with c# application, I wrote some code, I have the connection with the printer, but when I am sending codes it not responding. On the other side, I found Java application for sending control codes, from that app some of the codes is working but not all of them. For example I want to use ESC EM 66 control code but when I am sending this code, printer not responding or just print the code in numbers.
The code who I use is:
class Program {
public const short FILE_ATTRIBUTE_NORMAL = 0x80;
public const short INVALID_HANDLE_VALUE = -1;
[Code]....
When I am using the method GetDocument() printer is not responding, but it prints only text when I call the buffer variable:
I'm doing some file input/output work here in C and received this warning during compilation (GCC). My research indicates that this error is in response to white space or a character cancellation function or something like that. I'm not 100% sure exactly what it means. My code works fine, but the following warning does appear.
Code: warning: unknown escape sequence: '40'
Here's my code (excluding a bunch of comments at the bottom of the file).
I believe the error I received has to do with either the ' ' I used when appending text to my file, or something to do with there being a space in the file name itself.
I'm trying to get the current position of the cursor in the terminal window. I know that the ansi escape sequence " 33[6n" will display the current x and y location of the cursor. But what I can't figure out is how to store the x and y locations into their respective integer variables.
This is what I've done so far:
Code: #include <stdio.h> int main(void) { int line, column; char cursor_curr_pos[9]; char escape_sequence[] = " 33[6n"; //outputs x and y location of cursor e.g. ^[[18;1R snprintf(cursor_curr_pos, 9, "%s", escape_sequence); //save output to string sscanf(cursor_curr_pos, "^[[%d;%dR", &line, &column); //only read numbers from string }
I have a test web page and a windows form which call a printer and sends a print job to a printer that is on the network. I have been able to successfully do this from the windows form, however, I can figure out how to do it from an aspx page to the server's default printer. Sample codes are below.
Windows Form: public partial class Form1 : Form { private const string TEMPLATE_DIRECTORY = @"C:Program FilesBrother bPAC3 SDKTemplates"; // Template file path private const string TEMPLATE_SIMPLE = "NamePlate1.LBX"; // Template file name private const string TEMPLATE_FRAME = "NamePlate2.LBX"; // Template file name public Form1() { InitializeComponent();
My professor assign me a task to create a manual printer settings, not necessary same as printer setting the important thing to do is to have a combobox. In the combobox that you will see the available installed printers, and one command for print that if going to select one available printer in the combobox. It is possible ?
In my code, I wanted to write log exception to some file.
So I created a Utility class & wrote a static method in that to write log message to file.
public static void WriteLog(string message) { using (FileStream fs = new FileStream(@"c:log.txt", FileMode.Append)) { using (StreamWriter streamWriter = new StreamWriter(fs)) { streamWriter.WriteLine(message); } } }
This works fine so far but I fear if two methods call this function simultaneously.. what will happen? Also, I want to access this same Utility library in my other "WEB" projects... will it work there too?Or else.. what will be the best way to log exceptions in any project?
how to make write xml continuous from port COM. Port my COM receive data continuously from external hardware and now I want to record continuous data into xml file (overwrite)
In my application there is a structure that holds 200 parameters for 200 tests. These structure is converted to byte array . I want to write this byte array to a file in save button and when I click open button, this file must open and write these bytes to corresponding text boxes. How it possible.?
I want to open one new CMD from console application, write text into the new CMD and then coming back to the control on the old cmd. (like interactively working on the both)
look into the below code
Process P1 = Process.Start(@"C:WINDOWSsystem32cmd.exe"); P1.StartInfo.RedirectStandardInput = true; P1.StartInfo.RedirectStandardOutput = true; P1.StartInfo.UseShellExecute = false; StreamWriter wr = P1.StandardInput; wr.WriteLine("First line in New Cmd"); Console.WriteLine("First line in Old Cmd"); wr.WriteLine("Second line in New Cmd"); Console.WriteLine("Second line in Old Cmd");
it is giving the exception "StandardIn has not been redirected"
I need to create a GlobalConfig class. But I want to derive from it in another class.
Here's an example:
public class BaseConfig { public string GlobalPath {get; set;} } public class ConfigA : BaseConfig { public string pathA {get; set;} } public class ConfigB : ConfigA { public string pathB {get; set;} }
The idea behind is that I don't want to write the code multiple times and what's more important in class ConfigA I want to set GlobalPath and have access to it in ConfigB.
In other word I want class ConfigB to have a property GlobalPath which was set in class ConfigA.
To clarify I want to have only one object of Config in memory.
When I set BaseConf.GlobalPath to 'A', I want to access it from ConfigB.GlobalPath and also get 'A'.
I always design GlobalConfig as a static class, but static classes can't be inherited. So I tried to implement Singleton Pattern, but ConfigA can't find constructor of class BaseConfig because it's private.
take a look at this project : [URL] i want to change this project for this purpose : when a USB PRINTER is connected show a message that tell us -> hey this is a printer. which part of this project should i change and how can i separate printer devices from the others?
note: if you are using visual studio 2010 or higher and get error for this line after conversion :
#define _WIN32_WINNT 0x403
just replace all of such these lines to stdafx.cpp file. means stdafx.cpp at last should be like this :
// stdafx.cpp : source file that includes just the standard includes // HWDetect.pch will be the pre-compiled header // stdafx.obj will contain the pre-compiled type information #define _WIN32_WINNT 0x403 #include "stdafx.h"
I'm not new to C++ programming but I'm not an expert either. I'm using Borland C++ builder 5. I know it's extremely antiquated, but I have no choice right now. Writing a database reporting program, using third party report building components (ACE) which has it's own print dialogs built in. However, in this report we cannot use the build in dialogs and have to use a standard TPrintDialog. When the TPrintDialog is executed and you click print on the dialog, only one page is sent to the printer.
Here's some code:
// The dataset for the report is executed prior to this code and does not //change.
Once the data is gathered, the report can be run as often as you like // and the same data will appear in the report.
Write a program to simulate a printer queue (priority queue or heap – Bentley article has code) where 3 printers are “fed” by this queue. Each print job has an unchanging priority and higher priority jobs go first (although once started, a job isn't stopped to let a higher one go). For each unit of time, there is a 26% probability that a job will be added to the queue and all jobs take 8 time units to complete. Print job priorities are between 5 and 100. The queue opens 20 time units prior to the start of printing for adding print “jobs”. A print “day” is 1000 time units. The output from your program is:
1) A list of jobs completed with their priorities for each printer
I'm in the middle of creating a ePOS for my uncle and so far I've created a database for it where it will create, update and delete records successfully.
My next step I would like to do is to create a printer till thing, but how do I connect my database to that ?
I can create a till but how do I do link my database with it? I followed this example here [URL] ....
We have an assignment in which we have to implement a printer spooler using linked lists. I have used the list from STL to implement everything. I can get the program to send the print command and maintain status of documents. The problem is I don't know how to mimic/send a dummy print command so the document gets printed. If I use Sleep() there is a delay in the whole program.while I want printing on backhand and others users to have access to the program.
I have written a program to capture signal from machine and display it on screen in the form of sinosoidal wave. I have print buffer for 256 X 400 pixel strip chart. This prints fine if I set page size A4 and resolution 600 DPI. If anyone changes print parameters , there is problem. I can resize the printer buffer and interpolate the stored signal.
My problem is , how to find the printer resolution from GetDeviceCaps ? how to know the Print Type Normal / Draft etc in mFC.
I am using PDF Creator printer to print my files. I have set it as default printer. It displays two dialogs .. "Printer Setup Dialog" and "Dialog asking filename and other details to save to file".
I want to avoid these two dialogs. But EndDoc calls the other dialog by default. How to do this ?
I am trying to print a barcode form HClabel printer through my application running on Windows server 2008. The printer is a ntwork printer connected to a Windows 7 Machine.
The code to access the printer and proceed with printing is in VC++. The code has been working fine since years and it still works when I try to print from Windows XP machine(Connect and print on the same printer connected to WIndows 7 machine mentioned above).
The error code I receive when tried to print from windows server 2008 is 2 which says File not found. But when i access the machine from windows server 2008, it is accessible.
