Dear All,

I need to stop ejecting paper till dotted line after printing the data using dot matrix printer LX300+ II.
I have used below code.

C++

CPrintDialog dlgPrint(FALSE,PD_ALLPAGES,this);
dlgPrint.GetDefaults();
CDC dcPrint;
dcPrint.Attach(dlgPrint.GetPrinterDC());

//** Create and fill a DOCINFO structure
DOCINFO myPrintJob;
myPrintJob.cbSize=sizeof(myPrintJob);
myPrintJob.fwType=NULL;
myPrintJob.lpszDatatype=NULL;
myPrintJob.lpszDocName="MyPrintJob";
myPrintJob.lpszOutput=NULL;

//** Start the Printing document
if (dcPrint.StartDoc(&myPrintJob)>=0)
{
//**Start a page
dcPrint.StartPage();

    dcPrint.TextOut(250,150,"Weighment - Slip");
    dcPrint.TextOut(250,200,"Test data");


//** Throw the page
dcPrint.EndPage();

//** Close the document
dcPrint.EndDoc();
}
//** Delete the printer device context
dcPrint.DeleteDC();

I have tried using page setup.but no success....Kindly suggest.

Regards,

Dipti
P.S: I have searched in the forum but could not find the solution.

Solution 1

When you call dcPrint.EndPage it sends an end-of-page message to the printer.

If you have other things you want on the same page you need to include the code to print those things before the EndPage is called.

Solution 3

If you only want to print text using the printer built-in character sets, you can directly write to the printer by opening LPTx with CreateFile and using WriteFile.

This requires that you setup and control the printer using the Epson ESC/P[^] command set.

Then print your text and apply line or page feeds according to your requirements and the paper size.

[UPDATE: Example code]
I have not used ESC/P printing since DOS times. This is untested.

HANDLE hPort = CreateFile(_T("LPT1:"), GENERIC_WRITE, FILE_SHARE_READ, NULL,
     OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
if (hPort != INVALID_HANDLE_VALUE) 
{
    char lpszCmd[] = "Test\r\n";
    DWORD dwWritten;
    WriteFile(hPort, lpszCmd, strlen(lpszCmd), &dwWritten, NULL);
    CloseHandle(hPort);
}

[UPDATE 2]
The Windows API provides functions to perform direct printing by opening with the printer's name:
OpenPrinter, WritePrinter, and ClosePrinter.
Just use these instead of the above I/O functions.

Kindly share the sample code for opening LTP1 port and send commands.

Now printer does not eject paper after data is printed.Thanks a lot for the help.

I could write data in a single line using above code and its working fine without ejecting paper. However, I need to write data in a table format(6 rows and 4 columns). Is it possible with WriteFile?

Jochen Arndt 23-Dec-14 5:44am

It is possible by printing spaces between the cells and CR-LF (\r\n) pairs between the lines.

Ok.But how do I print the border of the table?

Jochen Arndt 23-Dec-14 5:53am

You must do it yourself by printing the special line characters that are part of the character set or use the ESC/P commands.
I have updated my question because the link to the ESC/P commands was wrong. Follow the link and download the PDF files to get the character tables and see what you can do.
