Yes, but the exact same thing is true of on-screen windows.  You can use 
GetDeviceCaps(hdc, LOGPIXELSX) to get the pixels per inch resolution.  
There's also a LOGPIXELSY, but unless you have a 40-year-old graphics 
adapter, they are the same.  The DeviceCapabilities API returns a 
DEVMODE structure that has detailed information about the printer.

Absolutely, yes.  Modern printers can be 300, 600, or 1200 dots per 
inch.  Label printers can use even wilder values.
