In PB9 -  printsend was used to send ( 4"X6" ) label specific printer codes describing the label layout to our label printers.

Label software LOFTWARE - Compiled files Labelname.dwn contains the layout definition ( template binary codes ) of the label and Labelname.dat contains the detail of the label ( binary code followed by fieldname/position on label ).

Since PRINTSEND is no longer supported in PB2017 - any ideas how to accomplish the same result - sending binary codes and data to a printjob ?

Thank you

Anton

 

In sample code below is shown the PRINTSEND function - dumping the the label template to the printer.

 ls_HeaderFile = ls_labelsdirectory + "LABELS\" + TRIM(lsLabelFile) +".DWN"
 
 IF ls_HeaderFile "" THEN
  IF FileExists(ls_HeaderFile) THEN
   // On Disk
   long ll_HeaderFileHandle, ll_HeaderFileSize, ll_HeaderLoopControl, ll_HeaderLineRead
   string ls_Line = ""
   ll_HeaderFileSize = FileLength(ls_HeaderFile)
   ll_HeaderFileHandle = FileOpen(ls_HeaderFile)
   ll_HeaderLoopControl = 0
0 THEN
    // Read the file one line at a time and print it out...
    DO WHILE ll_HeaderLoopControl
     ll_HeaderLineRead = FileRead(ll_HeaderFileHandle,ls_Line)
0 THEN
      ll_HeaderLoopControl = ll_HeaderLoopControl + ll_HeaderLineRead
      PrintSend(ll_PrintJob,ls_Line)
     ELSE
      IF ll_HeaderLineRead -100 THEN
       gnv_app.inv_error.of_Message("File read error on the header file '" + ls_HeaderFile + "'")
       lb_Return = FALSE
       EXIT
      ELSE
       EXIT
      END IF
     END IF
    LOOP
   END IF
   FileClose(ll_HeaderFileHandle)
  ELSE
   gnv_app.inv_error.of_Message("Cannot find the header file '" + ls_HeaderFile + "'")
   lb_Return = FALSE  // specified file does not exist.
  END IF
 END IF

// Routine processing the ls_DetailFile - Labelname.dat

etc.
