Printing Method Impact Dot Matrix
Number of Columns How it works?
Dotmatrix printers offers four options 136 columns, 132 columns, 94 columns and 80 columns. The choices depend upon the needs of the user.
Benefits
A printer that can print a higher number of columns can be beneficial if you need to print account sheets or balance sheets. 80
Number of Pins What it means?
This refers to the actual number of small metal pins on the printer head which strike on the ribbon and then on the paper to print a character.
How it works?
A printer can have either 9 metal pins or 24 metal pins. The print resolution of the printout taken by a 24-pin printer is higher as compared to the one taken by a 9-pin print head. If you need to print graphics on your Dot matrix printer, then you should opt for a 24 pin printer.
Benefits
A higher pin-printer gives a better quality printout. However, remember that there is very little quality difference between 9-pin and 24-pin models if the documents will be printed in draft mode. 24

Bit Image What it means?
A dot matrix image where each dot is represented by one bit in the digital memory. Complex images are built up using these dots. Resolution of about 300 dots per inch may require approximately I Mbyte for a complete A4 page.
How it works?
A collection of bits in memory that forms a grid-that is, a rectangular pattern of bits. The bit image is pointed to in the base address field of a BitMap record.
Benefits
A bit-map image is made up of small dots (pixels) arranged in a grid. The finer the grid, the higher the resolution of the image. Bi-Directional
