Related to Printer selection and selecting one of them programatically

[EMBEDED SOFTWARE FOR GUI OF A SPECTRUM A]

Hi ,

In my application I am using LW/CVI and my system is connected with more than one printer . Now I want to get Ids of all printers that are available and select one of them programatically for printing .Tell me what are the functions that can be used in this situation.

Regards

Subrata,

In order to specify a printer programmatically in CVI, you use the ATTR_PRINTER_NAME print attribute.

In order to browse the list of available printers, there is nothing in the standard CVI libraries that will allow you to do that. However, you can use the SDK function GetProfileString to return the list of installed printers. To do so, pass "PrinterPorts" as the first parameter, and NULL as the second parameter.

As well as the two parameters that Luis gave details for, there are three others that you need to supply as well. The prototype is as follows, but you should check out the SDK help for the function.

    DWORD GetProfileString (LPCTSTR lpAppName,
                            LPCTSTR lpKeyName,
                            LPCTSTR lpDefault,
                            LPTSTR lpReturnedString,
                            DWORD nSize);
