The word 'Drucker' (printer) is derived from the verb 'drucken' (to print). The ending '-er' in German can refer both to a person who performs an activity and to a tool or device that carries out that activity.
Der Bäcker backt Brot.
The baker bakes bread.
You can always tell from the context whether the device or the person is meant. Words like 'Tinte' (ink), 'Papier' (paper), 'installieren' (to install), or 'kaputt' (broken) point to the device. Terms like 'Ausbildung' (training/apprenticeship), 'Beruf' (profession), or 'Druckerei' (print shop) point to the person.
Ich muss für meinen Drucker neues Papier kaufen.
I need to buy new paper for my printer.
When referring to the device, 'Drucker' (printer) is often used with these verbs: 'einen Drucker anschließen' (to connect a printer), 'installieren' (to install), or 'einrichten' (to set up). The combination 'der Drucker funktioniert nicht' (the printer isn't working) is also very common.
Kannst du mir helfen, den neuen Drucker zu installieren?
Can you help me install the new printer?
When the person is meant, typical formulations are 'als Drucker arbeiten' (to work as a printer) or 'eine Ausbildung zum Drucker machen' (to do an apprenticeship as a printer).
Mein Onkel hat 40 Jahre lang als Drucker in einer großen Zeitung gearbeitet.
My uncle worked as a printer at a major newspaper for 40 years.
scanner
'der Drucker' and 'der Scanner' are both devices often used with a computer or in an office. The important difference is the direction: a printer turns a digital file into paper. A scanner turns a piece of paper or a photo into a digital file. The words can be confused because many modern devices can do both. If you want something on paper, you need 'der Drucker' (the printer). If you want to bring a paper document into the computer, you need 'der Scanner' (the scanner).

Der Drucker im Büro hat den Vertrag nur halb ausgedruckt.
The printer in the office only printed half of the contract.
Vor dem Termin habe ich den Ausweis mit dem Scanner kopiert.
