Hello!

I need automatically recognize the type of the POS printer which is plugged to my com port.
Now I need to list all of the com ports available in the system, then check every port.

How I can know the type(name) of POS printer without using any drivers and POS.NET?

What a COM port does is sending and receiving data what is attached to it.
What you're asking depends on the printer, and there is no standard way to get description data from them.
Every "enough intellingent printer" (but, already we are speacking of a subset of them) responds to certain particular character sequences by returning some descriptive text.
How this "sequeces" (aka "commands") are formed -unfortunately- depends printer by printer.

Every POS printer can print it's test page witch contain all information about settings of this device. It's possible get this information in programm?

I know it but should be another ways may be not so obvious, may be not depend on commands. Many commands in POS printer are equal.
