Final answer:
To list all printer's maker, model, and price in a SQL query, use the SELECT statement with the ORDER BY clause, ordering by price in descending order.
Step-by-step explanation:
To list all printer's maker, model, and price in a SQL query, you can use the SELECT statement along with the ORDER BY clause. Assuming you have a table named 'printers' with columns 'maker', 'model', and 'price', the query would look like this:
SELECT maker, model, price
FROM printers
ORDER BY price DESC;
This query will retrieve the maker, model, and price from the 'printers' table and order the results in descending order based on the price, displaying the highest price on top.
