是否有获取高级打印机设备设置的API？

Question

我需要通过win32 api获取特定打印机的可用支持打印机文档功能。

我所指的选项在下图中为示例打印机显示。您可以通过右键单击打印机图标和单击首选项并单击对话框中的高级选项卡来获得此对话框。

谁能告诉我需要的API我需要调用，并在其他什么？

我针对的是Windows XP +并使用vb6。

我认为你正在寻找的是winspool.drv的DeviceCapabilities。来自Microsoft的代码Sample。大部分文档的在线现在天是对于.NET，所以我在VB6定义类型从Dan Appleman's Visual Basic Programmer's Guide to the Win32 API

VB6的声明是：基于您的评论

Declare Function DeviceCapabilities& Lib "winspool.drv" Alias "DeviceCapabilitiesA" (ByVal lpDeviceName as String, ByVal lpPort as String, ByVal iIndex as Long, ByVal lpOutput as String, ByVal lpDeviceMode as Long) 

---

，你将需要使用DocumentProperties它可用于检索或修改DevMode结构。它可能会或可能不会有你在找什么。你最好的选择是获得上面的书，第12章有丰富的信息。同样看着你的照片，看起来你正在使用某种POS打印，你应该咨询制造商有关打印机可能支持的特定api的文档。

Declare Function DocumentProperties& Lib "winspool.drv" Alias "DocumentPropertiesA" (ByVal hwnd as Long, ByVal hPrinter as Long, ByVal pDeviceName as String, ByVal pDeviceModeOutput as Long, ByVal pDeviceModelInput as Long, ByVal fMode as Long) 

DEVMODE结构

Public Const CCHDEVICENAME = 32 
Public Const CCHFORMNAME = 32 

Type DEVMODE 
    dmDeviceName as String * CCHDEVICENAME 
    dmSpecVersion as Integer 
    dmDriverVersion as Integer 
    dmSize as Integer 
    dmDriverExtra as Integer 
    dmFields as Long 
    dmOrientation as Integer 
    dmPaperSize as Integer 
    dmPaperLength as Integer 
    dmPaperWidth as Integer 
    dmScale as Integer 
    dmCopies as Integer 
    dmDefaultSource as Integer 
    dmPrintQuality as Integer 
    dmColor as Integer 
    dmDuplex as Integer 
    dmYResolution as Integer 
    dmTTOption as Integer 
    dmCollate as Integer 
    dmFormName as String * CCHFORMNAME 
    dpBitsPerPixel as Integer 
    dmBitsPerPel as Long 
    dmPelWidth as Long 
    dmPelHeight as Long 
    dmDisplayFlags as Long 
    dmDisplayFrequency as Long 
    dmICMMethod as Long 
    dmICMIntent as Long 
    dmMediaType as Long 
    dmDitherType as Long 
    dmReserved1 as Long 
    dmReserved2 as Long 
End Type

的DeviceCapabilities函数是只读的。你要找的是DocumentProperties function。 DeviceCapabilities实际上是相当过时的，因为它假定只有一个用户和一个应用程序正在使用打印机，所以应该早已过时。您不想为每个打印作业设置打印机属性;您要为当前打印作业设置文档属性。 DocumentProperties函数将为您做到这一点，但请密切关注上面链接中有关如何进行更改的说明。这是一个不必要的复杂功能。
