Data caching!

Last week Kavin wanted to print something and he was asking Kabi to help him. But Kabi said that the printer is OFF and he doesn't know whether there is sufficient ink in the cartridge. So Kavin said let's switch it ON and find out.
But Kabi wanted to tease him so he kept on asking him how they could know the status of cartridge without switching ON the printer.
Kavin kept thinking and said-"Maybe the computer has stored the cartridge info last time it was connected to the printer. So we should check the computer to find out the level of the ink and then we can print the page."
Talking about data caching!
Unfortunately our printer software doesn't support that.But good thinking!
