By default, Calc is configured to do just that. But the setting can be changed so that only the current sheet is printed too. Go to File > Print > Options and then tick the box labeled Print only selected sheets for Document. To make the change permanent for all occurrences of OOo Calc, go to Tools > Options > Spreadsheet > Print and select the same option: Print only selected sheets for Document.
