Windows C++ / Connected Printer by fr0gger
Created the Sunday 19 March 2023. Updated 6 months, 1 week ago.
Description:
This code uses the Windows API function EnumPrinters
to enumerate the local printers installed on the system. If EnumPrinters
is successful, the code prints the number of printers found and their names.
Code
#include <windows.h>
#include <winspool.h>
int main() {
DWORD numPrinters;
PRINTER_INFO_2* printerInfo;
if (EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 2, NULL, 0, &numPrinters, NULL)) {
printerInfo = (PRINTER_INFO_2*) malloc(numPrinters * sizeof(PRINTER_INFO_2));
if (EnumPrinters(PRINTER_ENUM_LOCAL, NULL, 2, (LPBYTE) printerInfo, numPrinters * sizeof(PRINTER_INFO_2), &numPrinters, NULL)) {
printf("Number of printers found: %d\n", numPrinters);
// Print the names of the printers
for (DWORD i = 0; i < numPrinters; i++) {
printf("%s\n", printerInfo[i].pPrinterName);
}
}
free(printerInfo);
}
return 0;
