set default printer

[vix]

Hi,

I wrote a small vi (LV 7.0) to get/set default printer, but it doesn't work at all.

If I set one of the available printers as default (for example PDFCreator), when I re-start my test vi, I read that default printer is PDFCreator, so it seems OK. But under Settings --> Printer I can see that default printer isn't changed, and if I give a print command this printer is activated (and not PDFCreator).

If i set another printer as default, the behavior is exactly the same.

I tried my vi on:

- Win XP SP1

- Win 2k SP4

and no differences.

Any suggestions to programatically set default printer on Win 2k and Win XP?

Thanks in advance.

Hi

If you right-click one of your property-nodes (pr.defaultprinter) and select help for printing:defaultprinter, you will see that this information is just valid in the LV-environment. The system is not affected by these properties.

so, if I use the method "Print Panel to Printer" I can change the default printer (in LV environment) as I want (I checked), but if I use the Print HTML Report (which send print command from a browser) this is impossible.

Correct?

No solutions?

What do you mean with "Print HTML Report"? The standard report vis? If yes - there should be able to pass the printer you want to print to.

The Report Generation VI, with report type = HTML (not standard report).

Only for a standard report, not for a HTML one.

I find in the Print Report.vi help:

"printer name is the name of the printer to which you want to print the report.

 If you print an HTML report, the VI ignores this input and uses the default printer for Internet Explorer. "

So will have to change the corresponding entries in the registry - but I don't know which keys you have to change.

I found the documentation on Microsoft Web Site: the registry is

HKEY_CURRENT_USER

Software\Microsoft\Windows NT\CurrentVersion\Windows

I wrote a small VI and it works well (on Win XP)

Could you explain it better?

Thanks for your replay

为了能把意思说明白，请允许我用汉语。

控制面板里，默认打印机里有个打印首选项，里面可以选择比如纸张大小，方向，效果，打印速度等等。

我现在想在LV里实现这些，这样就不用打开打印机里的哪个设置了，或者在LV中把这个设置页面调出来也可以。

目前的问题是：

 使用上面的程序可以把设置页面调出来，也可以修改比如纸张大小啊之类的，但是实际上打印出来的还是在默认打印机里

打印首选项里的设置。也就是说上面的程序的设置并没有起到作用。

LVSetDefaultPrinter 里面有哪些参数？在哪里可以看到或者找到，

Thanks in advance~~~~
