Determine whether the current computer has a printer

You can use the getprofilestring function to obtain the default printer information. If the default printer fails to be obtained, the current computer does not have a printer.

The C ++ code is as follows:

Bool isexsitprinter ()
{
Tchar tszprinter [128] = {};
DWORD dbytecnt = 0;
Dbytecnt = getprofilestring (_ T ("Windows"), _ T ("device "),
Null, tszprinter, 128 );
If (dbytecnt <= 0)
{
/* The current computer does not have a printer */
Return false;
}

/* The current computer has a printer */
Return true;
}

Among them, _ T and tchar can be used for both asni and Unicode encoding methods.
