options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--test-type");
DesiredCapabilities cap = DesiredCapabilities.chrome();

Are you using Adobe Acrobat/Adobe Reader to display the PDFs? If so, it is probably Abode's behavior you need to modify.
您是否使用 Adobe Acrobat/Adobe Reader 来显示 PDF？如果是这样，则可能是您需要修改 Abode 的行为。
Here are the steps I had to take:
以下是我必须采取的步骤：
- Open Adobe Reader
- Edit menu, Preferences
- Selcet Internet from the Categories list
- Uncheck Display PDF in browser
- Press OK
- 打开 Adobe Reader
- 编辑菜单，首选项
- 从类别列表中选择 Internet
- 取消选中在浏览器中显示 PDF
- 按确定
you can also disable the Adobe plugin in Chrome, which will force Chrome to download the PDF.
您还可以在 Chrome 中禁用 Adobe 插件，这将强制 Chrome 下载 PDF。
It's under chrome://plugins.
它在 chrome://plugins 下。
but as you said its latest chrome browser then check is chrome PDF view visible in plugin if Yes disable it too.
但正如你所说的，它最新的 chrome 浏览器然后检查插件中是否可以看到 chrome PDF 视图，如果是的话也禁用它。
- Disable "Chrome PDF Viewer" or unmark always allowed to run check box try both
- 禁用“Chrome PDF 查看器”或取消标记始终允许运行复选框尝试两者

You would need to add below statement to your chrome profile:
您需要将以下语句添加到您的 chrome 配置文件中：
chromePrefs.put("pdfjs.disabled", true);
It seems that newer versions of browsers are coming with built-in ability of displaying PDF files inside browser. Refer thisfor more information, though it is for firefox profile but still a good read.
似乎较新版本的浏览器具有在浏览器中显示 PDF 文件的内置功能。有关更多信息，请参阅此信息，尽管它适用于 Firefox 配置文件，但仍然值得一读。
Hope that solves your issue, else you may need to downgrade your chrome to make it work. Let me know if you have any queries.
希望能解决您的问题，否则您可能需要降级 Chrome 以使其正常工作。如果您有任何疑问，请告诉我。

Since chrome 57 the automatic pdf preview no longer works as a plugin, there's now a setting you can change to make this work. You can actually inspect the name of the pref by inspecting the chrome's own preference dialog, under "Content Settings" the flag that says "Open PDF files in the default PDF viewer application."
由于 chrome 57 自动 pdf 预览不再作为插件工作，现在您可以更改设置以使其工作。您实际上可以通过检查 chrome 自己的首选项对话框来检查首选项的名称，在“内容设置”下，“在默认 PDF 查看器应用程序中打开 PDF 文件”的标志。
You can set that to false to avoid automatic pdf preview, like this (ruby example):
您可以将其设置为 false 以避免自动 pdf 预览，如下所示（ruby 示例）：
caps = Selenium::WebDriver::Remote::Capabilities.chrome(
"chromeOptions" => {
'args' => ['disable-gpu', "--window-size=1920,1080"],
prefs: {
"download.prompt_for_download": false,
"download.directory_upgrade": true,
"plugins.always_open_pdf_externally": true,
"download.default_directory": DownloadHelpers::PATH.to_s
}
}
)
Capybara::Selenium::Driver.new(
app,
browser: :chrome,
desired_capabilities: caps
)
