I have a Nikon cooplix L18, I took a pictures with the date on, I want to print without date How can I do it?

Not without special software to change the EXIF data of the file. You could Google Exif Date change" and pick from the software in the results. If it is a date that is part of the visible photo (even shows up on prints of the photo), you would have to use a photo editing program such as Photoshop.

Use a card reader to download your pics to a folder you create on your desktop.

You'll need to use a photo editing program like Photoshop Elements to erase the date. Is the date close enough to the edge that you can crop it out?

This is probably THE single most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

Sounds as if the card is corrupted - you will have to use data recovery software.

We were in the middle of taking pictures on our Nikon L18 and it was in continuous shot mode and the picture froze on the screen...I called tech support and they wanted me to turn the camera in so it could i fixed..it was a BRAND NEW CAMERA!!!!
yeah so we just took the batteries out and let it reset...see if that works.

reset ALL settings to factory defaults.also remove meoryh card and batteryh then refix both.then check .

hey dear you must have got the battery and charger along that charge those batteries for 8 hrs and then use coz nikon doesn't have LI ion battery so u have to charge the cells instead

The camera needed to be replaced.

Try this, it may work without the software.  Turn off the camera. Plug the usb cable between the camera and the computer. Turn on the camera. If a box pops up on the computer asking what you want to do, scroll down and see if there is an option to view pictures. If a window opens up with all your pictures on it, great. Now open up a folder where you want to put your pictures. Bring up the other window with the pictures in it and hit the control key and the d key at the same time on your keyboard. Then drag your pictures to the window where you want them and let go of the mouse key.  They should all move over. Then you can use Windows image viewer to see them. Let me know if that works.
