How print continuously in a HP 2550 color laserjet with legal size paper? -

I have a 2550 hp color laserjet printer, when i print with legal size paper the printer stops in every sheet, so i have to go to the printer and push the green button to continue printing another sheet, but when i print with letter size that not happen the printer prints continously.

It may be in your printer properties. When you go file print you should see a box come up that has a properties button. Click on it and see if shows you the properties for your printer It should have a place somewhere to tell it to print aumatically without having to push the button everytime for each page.
