Visual C + + PRINT programming technology-programming basics-Getting a printer

The standard method is to use the: EnumPrinters () function to obtain

#define Printer_enum_default     0x00000001#define printer_enum_local       0x00000002#define printer_enum_ CONNECTIONS 0x00000004#define printer_enum_favorite    0x00000004#define printer_enum_name        0x00000008#define Printer_enum_remote      0x00000010#define printer_enum_shared      0x00000020#define printer_enum_network     0x00000040
