Hi Vlad,

First, thanks for your help. What I wrote was a modification of MS KB Article Q140285Q140285 (How to modify printer settings using SetPrinter).

Anyway, after changing the printer handle from LPHANDLE to HANDLE, and the parameter passing required. It still didn't work. Then, on a guess, I removed changed the following:

/* Removed the following */
dSize = sizeof(prninfo)
/* Changed */
GetPrinter(iHandle, level, (LPBYTE)prninfo, dSize, &numbytes);
/* to the following */
GetPrinter(iHandle, level, (LPBYTE)prninfo, numbytes, &numbytes);

Then I could get the attributes correctly. However, the status must only be available after a print job has been set.

Anyway, thanks for the help.
