Gambit, To answer your questions: I was getting the wrong page sizes with: (A) Printers()->PrinterIndex=x; width=GetDeviceCaps(Printers()->Handle, PHYSICALWIDTH); which was corrected when I did: (B) HDC HPrinterDC = CreateDC(NULL, Device.c_str(), NULL, pdm); width=GetDeviceCaps(HPrinterDC, PHYSICALWIDTH); or: (C) HDC HPrinterDC = CreateIC(NULL, Device.c_str(), NULL, pdm); width=GetDeviceCaps(HPrinterDC, PHYSICALWIDTH); which lead me to notice that the Handle returned by (A) was not the same as returned by (B) or (C) when accessing a printer that is other than the default printer. I tried CreateDC because in was already coded from an example I was lead to by another poster Vladimir. I tried both for the heck of it; what's the difference? The application: The application needs to print on three different printers, one is portrait letter text , the second is landscape letter graphic, and the third (where the problem is most obvious) prints on one of three sizes of continuous feed address labels. The first two are laser or bubble jet printers, the third is a dot matrix printer with tractor feed. And the problem: (which I have spent the better part of the week on) I have the first two woking fine, but the problem started when I was trying to get the page size for the label printer using (A) from above. I finally was able to get the page size corrected using GetDeviceCaps if I manually changed the default printer (which isn't practical in the end application). The issue of having the wrong handle was masked by the fact that I was selecting and printing to the correct printer but on the wrong size paper. So, prior to realizing the handle was wrong I figured that the page size was not getting from the printer settings to GetDeviceCaps and starting looking for a way to set the page size in the program. Now that I know the TPrinter::Handle is wrong, can (A) be fixed or do I have to go with (B) or (C)? Thank you for your time.
