The drip-type coffee is available in many countries in Europe. A list of names:
- Filterkaffee in Germany / Austria / Switzerland
- filterkaffe in Denmark and Sweden
- filterkoffie in the Netherlands
- kawa filtrowana in Poland
- café filtre in France / Switzerland / Belgium
- café filtro in Spain
- caffè preperato con il filtro in Italy / Switzerland
Can you see a pattern here: Always a combination of coffee and filter/filtered. The terms are so closely related that if you order "filtered coffee" an attentive waiter should be able to help you even if you don't know the precise term at your destination.
Note that if you order "coffee" without specifying the preparation, you will be served the local "default". This will actually be filtered coffee in many countries of Northern and Central Europe, in Italy, as counter-example, you will get what you'd call "espresso", likewise in Spain or Portugal: small, strong.
Asking for caffè americano will perhaps get you an espresso diluted with hot water in some places in Italy (sources vary whether it's a remenant from WW II or started with international tourism), sometimes caffè all'americana ("coffee American-style") will get you drip coffee. Likewise in touristy areas of Spain, café americano might get you a diluted coffee.
Further north you won't be understood. They will probably direct you to the nearest Starbucks.
Living and travelling in Europe for decades plus some research for the precise terms.
