How do I take a picture at 300dpi - Canon PowerShot A630 Digital Camera

First I'm asking you, what model of printer do you have? Check if the printhead installed is a 300dpi one. Also check if the model of printer is 300dpi configuration by verifying the "printer part number/serial number" label. If the printer is a 300dpi model and the printhead was changed with a 200dpi, all the label content will be printed bigger, just like you described.

you might have a 203dpi print head in one. you will physically have to remove and check the part # on the print head to verify it is a 300dpi [email protected]

Yes, in menu slect image size to small

The DPI (dots per inch) number only has meaning when printing the picture. It's meaningless to a camera.
The M1093IS takes photos that are 3672 x 2748 pixels at its best resolution. If you make a 4x6 print of one, you'll be getting more than 600dpi. If you make a 8x10 print of the same picture, you'll only be getting about 300dpi. Yet they're made from the same image file.
If you must change the image file itself, open it in just about any photo editor, change the DPI field, then save the file. Make sure you do this to a copy, not the original.

Print configuration from both printers and compare. Print config- Hold cancel button 10 sec. while power on. Check Resolution parameter. 203dpi=8MM Full , 300dpi=12MM Full. Sounds like perhaps they are different dpi.

I have canon lbp 2900 printer

in this printer i want to prit picture in 300dpi resoulition

how to print, that way i want printer 300dpidrivers

Forget 72dpi. Photoshop opens the picture in 100%.
1 pixel on the monitor is one pixel from the camera.
300dpi is only relevant when making prints, where 300dpi is the highest quality you can get from a lab.
The smaller the print, the more dots you get per inch.

Not really, since "300 dpi" is a print resolution specification. The camera takes pictures at whatever resolution you have set (0.3MP to 7.1MP on the A570).

If you print a 0.3MP photo at 300dpi, you'll get a picture 1.6 inches by 2.1 inches (smaller than a business card). If you print a 7.1MP photo at 300dpi, you'll get a picture about 8 inches by 10 inches. You can also get an 8x10 from the 0.3MP if you print at 60dpi, but the result will be rather grainy.

Again, "300 dpi" has no meaning to the camera.

Hi,
Yes your camera will give images with 300dpi . You need to set the dimension as 3264 x 2448.

Hope this helps.

You have to scan the pictures with a higher resolution to be able to print them in a larger format with acceptable quality.

If your default scanning setting is, say, 150dpi resolution, and you want the picture to be enlarged twofold, then you have to increase the resolution to 300dpi. If you have 300dpi now, increase it to 600dpi.
Some scanner utilities do a fully automatic scan - then you have to find the automatic scan settings and change the default resolution. Or better yet, find an option for a non-automatic scan, where you are presented with various options after the preview scan has been done. There you can usually set the desired size, resolution, improve contrast, sharpness etc.

Generally, the higher the scanning resolution, the more detail you have on the picture, and the higher magnification you can obtain when printing without quality loss.

But there's a catch - a picture in higher resolution produces a bigger file on disk - the file size grows faster then the resolution - a two times bigger picture will be four times bigger on disk. So you have to make sensible choice.
