LASER PRINTER :-
A laser printer uses, you guessed it, laser technology to create an image that is transferred to a carrier, such as paper or film. The laser can’t be beat for high resolution graphics and text. Prices have come down so that some low-end laser printers costs only about twice as much as dot matrix.
TIP :-
When considering the price of a laser, check out the cost for consumables as well-toner catridges and replacement drums can be expensive.
As with most other hardware, lasers come in different flavors. They may be capable of printing at 300, 400, 600 or 1200 dpi. Anyone preparing output for reproduction should consider a 600 dpi printer; a resolution of 300 or 400 dpi is adequate, but 600 guarantees that no compromises will be made when reproducing a fine line typeface or graphic image. Some manufacturers also have proprietary systems for smoothing images so that 300 dpi output is not the same for all printers.
TIP :-
If you expect to require laser quality only occasionally, consider using a copy shop or service bureau for your laser printing. Most have high resolution printers that can output from Post Script files. Check with the vendor for exact specifications, but generally you can assign the printing to a PostScript printer, then print to a file to take to the copy shop or Service bureau.
POSTSCRIPT :-
The page description language used by Aldus, originally for the Macintosh computer. PostScript is designed to be more precise with graphics then PCL although the gap has narrowed considerably. Most Service bureaus conform to the PostScript standard.
PCL (PRINTER CONTROL PROTOCAL) :-
A common protocol for laser printers used by Hewlett-Packard and Printers compatible with H_P.
A laser printer can also transfer images to film, a handy option if much of your work goes directly to a printer. Most service bureaus can accommodate out-put to film as well.
