What are the minimum margins most printers can handle?


Im making a PDF to sell, creating my orignal copy from a scanned paper, then I'm going to import it to acrbat and add fields.

I want it to be printable on any printer.
The use margins of 1" all around seems like a bunch of wasted space

The govenment doc I'm working on making digital has .42 and .46 left and right margins. but when i put that into my doc it says error.
even .50 errors
I dont even have a printer installed?is that why?


i was going to do trial and error till i found the smallest but now Im not getting the error on any size and wouldn't that be based on my printer anyway.

is .50 a safe bet for most printers
