Setting print quality

[unknown]

Hi,

i experienced the following behaviour:

Is used SetPrinter to change a printers "Print Quality" setting to
DMRES_something.
After the successful call, i used GetPrinter to re-read the settings but now
the dwPrintQuality member of the DEVMODE structure doesn't contain
DMRES_something, but some resolution in DPI!
Another quite strange behaviour is, that I have a printer driver which maps
two of the four DMRES_* values to the same DPI values.

My problem is, that I want to display the current settings using radio
buttons which represent the DMRES_* values, but it's difficult with DPI
values, because I don't know which values the printer supports.

Has anybody an idea how i can solve this problem and if it's possible to map
DPI values to DMRES_* values?

Thank you very much!
Max

It doesn't sound strange to me that two of the predefined values
happen to map onto the same DPI.

You can use DeviceCapabilities with DC_ENUMRESOLUTIONS to get the
resolutions that the printer supports.

Heres some additional information:

I'd like to change the default document settings for a printer.
Currently I use the following method:

1. Open Printer
2. GetPrinter (Level 2)
3. If no DEVMODE is returned, I use DocumentProperties to get it.
4. Modify the dmPrintQuality member.
5. Use SetPrinter (Level 2) to set the new settings.

I read in the MSDN that DocumentProperties MUST be called to verify the
DEVMODE-Settings, but I don't know exactly whats meant by this.

Has anyone some hints for me?

THANKS VERY MUCH!

By calling DocumentProperties(...), you ask the device driver to verify the
settings and make them proper. For e.g:- if you specify dmduplex to be
duplexing and pass to a printer driver whose printer capabilities says the
printer can't support duplexing , the device driver will turn it back to
non-duplex the dmduplex member of devmode and return the devmode back.

Do you understand?
