Inkjet Printers
By Stephen Bucaro
Because Laser printers use a process similar to photography, they will always
produce higher resolution results than inkjets printers. Laser printers are
also faster than inkjet printers. Laser printers cost less to operate because
inkjet cartridges are expensive and need to be changed more frequently than
toner cartridges, and because special coated paper is required to produce
high-quality output on an inkjet printer.
But the initial cost of an inkjet printer is much less than a laser printer,
and inkjet printers are required for certain projects, for example they can
handle heavy cardstock better for producing greeting cards. An inkjet printer
is also required to print on iron-on transfer paper. Laser printers can't be
used to print on iron-on transfer paper because they use heat.
In operation, a print head moves horizontally across the page and colored ink
droplets are squirted at the paper. Inkjet print heads contain between 300
and 600 nozzles, each about the diameter of a human hair. Typically between
four and eight cyan, magenta, yellow, and black colored ink droplets are
combined to create halftone colors.

Calculators for Your Web Site : Body Mass Index
By Stephen Bucaro
To determine if you are overweight physicians use your body mass index (BMI).
BMI is a formula that was developed in 1869 by the Belgian mathematician
Adolphe Quetelet. BMI is calculated by dividing your weight in kilograms
by your height in meters squared.
If you have a Web site related to health or dieting, or you just want to provide
more useful features on your Web site, you can provide a BMI calculator. The user
enters their height and weight into the calculator and receives their BMI as a result.
In this article I'll show you how to code a Java Script BMI calculator for your Web site.
I will explain everything in detail, so even if you have no programming experience you
can easily do this. Or you can just cut and paste the code into your webpage. The
first thing you need is a form for the user to enter their height and weight.

communicates. To choose an effective color scheme for your website requires a basic
understanding of color theory.
