PRINTER_ENUM_NAME = &H8 Get information about all the printers under the network domain specified by name. Win 95/98 for some reason also considers network printers to be local.

PRINTER_ENUM_LOCAL = &H2 Get information about local printers (the ones directly connected to the system). PRINTER_ENUM_DEFAULT = &H1 Win 95/98 only: Get information about the computer's default printer. PRINTER_ENUM_CONNECTIONS = &H4 Win NT only: Get information about the network printers which the computer has made connections to. CopyMemory, however, can be used to copy the data structures which make up parts of the PRINTER_INFO_2 data structure.įlags One or more of the following flags specifying which printers to find information about (note that PRINTER_ENUM_LOCAL and PRINTER_ENUM_CONNECTIONS are the only valid flags when using PRINTER_INFO_4):

In order to convert a Long-type string pointer (in the array) to a string, variants of the lstrcpy and lstrlen function must be used. Look at the two examples for details how. Instead, each individual member of the data structure must be set manually. Also, for some reason the CopyMemory function cannot be used to successfully transfer the array information into the structure. Note for Visual Basic users: Due to limitations in the Visual Basic language, it is impossible to pass an array of PRINTER_INFO_* structures as pPrinterEnum - the array must be of Long-type elements. The function returns 1 if successful, or 0 if an error occured. The information itself is put into the array passed as pPrinterEnum, which can then be copied into an array of data structures.

The attributes of the chosen structure determine what kinds of information about the printer(s) is returned. Note that structures 4 and 5 are the quickest ones to use. Under Win NT, the information can be passed in a PRINTER_INFO_1, PRINTER_INFO_2, or PRINTER_INFO_4 structure. Under Win 95/98, the information can be passed in a PRINTER_INFO_1, PRINTER_INFO_2, or PRINTER_INFO_5 structure.

These include both local printers (physically connected to the machine) and network printers (accessible via the network). Declare Function EnumPrinters Lib 'winspool.drv' Alias 'EnumPrintersA' (ByVal flags As Long, ByVal name As String, ByVal Level As Long, pPrinterEnum As Long, ByVal cdBuf As Long, pcbNeeded As Long, pcReturned As Long) As LongĮnumPrinters finds and returns information about one or more printers which the computer has access to.
