Final answer:
To pluralize the sentence, change the definite articles and the noun to their plural forms.
Step-by-step explanation:
In French, nouns have different forms depending on whether they are singular or plural. To pluralize the sentence "Il y a une imprimante sur la petite table", you would need to change the definite articles and the noun to their plural forms. The plural forms of 'une' and 'imprimante' are 'des' and 'imprimantes' respectively. Therefore, the pluralized sentence would be "Il y a des imprimantes sur les petites tables".
