Список установленных принтеров в системе (информация берется из реестра [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Devices] и [HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\PrinterPorts])
uses ..., Printer; ... var Printer: TPrinter; begin Printer := TPrinter.Create; try Memo1.Clear; Memo1.Lines.AddStrings(Printer.Printers); finally Printer.Free; end; end;
Если в имени присутвует сетевой путь - это сетевой принтер
Имеется еще EnumPrinters

The EnumPrinters function enumerates available printers, print servers, domains, or print providers.

BOOL EnumPrinters( DWORD Flags, // printer object types LPTSTR Name, // name of printer object DWORD Level, // information level LPBYTE pPrinterEnum, // printer information buffer DWORD cbBuf, // size of printer information buffer LPDWORD pcbNeeded, // bytes received or required LPDWORD pcReturned // number of printers enumerated );

У нее есть DWORD Flags, // printer object types

Flags [in] Specifies the types of print objects that the function should enumerate. This value can be one or more of the following values. Value Meaning PRINTER_ENUM_LOCAL The function ignores the Name parameter, and enumerates the locally installed printers. Windows 95: The function will also enumerate network printers because they are handled by the local print provider. PRINTER_ENUM_NAME The function enumerates the printer identified by Name. This can be a server, a domain, or a print provider. If Name is NULL, the function enumerates available print providers. PRINTER_ENUM_SHARED The function enumerates printers that have the shared attribute. Cannot be used in isolation; use an OR operation to combine with another PRINTER_ENUM type. PRINTER_ENUM_DEFAULT Windows 95: The function returns information about the default printer. PRINTER_ENUM_CONNECTIONS Windows NT/ 2000: The function enumerates the list of printers to which the user has made previous connections. PRINTER_ENUM_NETWORK Windows NT/ 2000: The function enumerates network printers in the computer"s domain. This value is valid only if Level is 1. PRINTER_ENUM_REMOTE Windows NT/ 2000: The function enumerates network printers and print servers in the computer"s domain. This value is valid only if Level is 1.

Бери и вычисляй, те которые тебе нужны
