Setting printer resolution programmatically

[cmarsura]

Hi, how can I set programmatically the printer resolution ?
In the PDF-XChange Driver API manual I cannot find any reference to this property, but the property appears in the printer dialog.
I tried

Code: Select all

PDFPrinter.Option("Paper.Resolution") = 600

or

Code: Select all

PDFPrinter.Option("Paper.Dpi") = 600

, but I got an error.

Is this an unimplemented property?

Thanks

Hello cmarsura,

I believe that you will need to set the DPI through the Devmode dmPrintQuality:

You can also set dpi using

Code: Select all

PDFPrinter.Option("DevMode.DPI") = 600

I tried to set the "DevMode.DPI" but to me seems to be supported but ignored.
I discovered also the "DevMode.Orientation" property but also this is ignored. Properties like "Paper.PageScale" or "General.Specification" are correctly supported instead.
I am using the version 4.0.195 of your printer.

See my included vbs with results, where I test the original "PDF-XChange 4.0" (with its defaults) vs. the the temporary printer created.

Can you verify this?

When you are making changes to the DEVMODE via the PDFPrinter object, you have to call

Code: Select all

PDFPrinter.ApplyOptions(0)

The Parameter of this function is reserved for now and must be 0 (zero).

Regarding these lines in your code:

Code: Select all

'This property is supportet but appears to not be honorated
PDFPrinter.Option("DevMode.Orientation") = -1

Orientation can have either of these values : DMORIENTATION_PORTRAIT (value is 1) and DMORIENTATION_LANDSCAPE (2).

That should resolve your issues.

Applied your suggestions - now everything works well as expected.

Thank you very much for the promptly response, your support is good as ever.

PS: if you can, update the pdf manual with these two new properties, so all users can take advantage of this.

Glad to hear that everything is working now Carlo,

And I will pass this topic to the guys responsible for the manuals, so that this information gets included there.

Cheers,

Hi Stefan,
DevMode properties has not yet documented in the printer manuals.

Cheers.
Carlo.

Hello Carlo,

Yes they are not -as they are documented here:
http://msdn.microsoft.com/en-us/library ... s.85).aspx

Best,
Stefan

I am not referring to the DevMode documented in MSDN but instead to the object accessible via PDFPrinter.Option(), as suggested by Ivan in this thread here https://forum.pdf-xchange.com/ ... 887#p49552.
However, documentation does not clearly states that you can set the DevMode properties through a syntax like:

Code: Select all

PDFPrinter.Option("DevMode.DPI") = 600

.
Best.
Carlo.

Hi Carlo,

Sorry - seems I got the situation wrong. I will once again pass this thread for reviewing by the people working with the manuals and we will see to get this corrected.

Best,
Stefan
