For Your Files

Doug Gogerty, technology specialist, talked about laser versus ink jet printing. "Your laser [printer] will do a little bit better, [be] better quality. That's one of the advantages of it. It will use different paper; you can use essentially ordinary paper on a laser, whereas it's better to use ink jet paper in an ink jet [printer]. Regular paper will absorb the ink and it will smear."

Doug also explained what a printer driver does. "A driver tells your computer software or your operating system (MAC or Windows) what¹s the capability of the printer: does it do color, or does it do black and white, [and] does it print on both sides of the paper or not."

Nicky Torkzadeh told us how to get a good print out of photos. "For photographs you generally want to be around 300 to 600 dots-per-inch on the printer side."

Nicky gave us some more advice on getting good printing of our photos. "To reduce that pixellation you actually have to change your resolution or pixels-per-inch on your printer. The way you do that is by reducing the image size. When you reduce the image size you're actually jacking up the resolution, [and are] also increasing the pixels-per-inch."

Tech Terms

Driver
Software that communicates between hardware, such as a printer, and a computer's operating system.

Pixellation
When the resolution of an image is too low and the pixels that make up the image are visible.

Resampling
Reducing an image's size to increase the resolution without reducing the number of pixels.

Resolution
The number of pixels per inch in an image, or the number of dots per inch used by an output device.
