The job of a printer is to put on paper what you see on your monitor. A successful print job must be easy to do and give you a document that looks like what you saw on the screen. That makes for a happy day!

Monitor screens and printers do not use the same formatting rules. In the olden days of computers, the way something looked on the screen could be VERY different from how it would look when printed.

Early word processors didn't have a way to show what the printed version would look like. Nowadays a word processor that doesn't have print preview, would be laughed off the shelf. We expect to see a WYSIWYG view (What You See Is What You Get), where you see almost exactly what the document will look like in print, while you are still working on it.

How fast?

The speed of a printer is measured in several ways:
cps   = characters per second
lpm   = lines per minute
ppm   = pages per minute

The faster the printing, the more expensive the printer.


What paper type?

Continuous-Form Paper

Continuous form paperOld style: Sheets are connected together with a strip of punched holes running down each side. The pages unfold in a zigzag. After printing, you can tear the pages apart and tear off the punched hole strips. Those holes are used to pull the paper through the printer.

This kind of paper is not used as often as it once was. It is still used with sheets of forms and receipts that make multiple copies with carbonless paper (using old-style dot-matrix printers).

Advantage:
  • Don't need to put in new paper often.
  • Can make multiple carbon copies.
Disadvantage:
  • May need to separate the pages and remove the strips of perforations from the edges.

Single Sheet

Reams of paper

Advantage:
  • Can change to special paper easily, like colored sheets, letterhead, card stock, or envelopes.
  • Can print on both sides, either in a duplex printer or by running the page back through.
Disadvantage:
  • Must add paper more often.
  • Cannot do carbon copies.

Media Types

What sizes and what materials can the printer handle? Legal length sheets? Banners? Envelopes? Card stock? Photo paper? Overhead projector transparencies? Index cards? Which choices, if any, matter to you?


What print quality?

LQ Letter Quality = as good as best typewriter output
NLQ Near Letter Quality = nearly as good as best typewriter output
Draft used internally or for a test print

The better the quality, the slower the printing.

A measure of print quality using numbers is printer resolution . Measured in dots per inch ( dpi ), this determines how smooth a diagonal line is when printed. A resolution of 300 dpi will produce text that shows jagged edges only under a magnifying glass. A lower resolution than this will produce text with stair-step edges, especially at large sizes. Even higher resolutions are needed to get smooth photo reproduction.

Professionals in graphics use 1200 to 2400 dpi printers. Draft quality on such a printer would be 600 dpi.


What will it print?

Moden printers can handle a lot more than old printers could. But, you still need to know the limits of your printer to avoid unhappy surprises! Yes, there are still old, clunky computers and printers in use out there in the real world.

Terms to know about printing:

Typeface Set of letters, numbers, and special characters with similar design
Sample fonts
Styles Bold, italic, underlined...
Size

Is measured in points
One point = 1/72 of an inch like:
12 pt
18 pt 24 pt 36 pt

Use 10 or 12 pt for writing a letter or report.

Font A complete set of letters, etc. in the same typeface, style, and size
Color Printing in color takes longer, uses more expensive inks or toner. Color printing looks best on more expensive papers, but can add a lot to the quality of the output
Graphics Pictures add a lot to a document, but not all printers can print graphics. In particular, dot matrix printers do not print images. Photos come out better with special photo ink and photo paper using a photo printer.
Duplex Printing on both sides of a sheet of paper. For less expensive printers you must physically turn the pages over and put them back in for printing. More expensive printers can print on both sides automatically.

Will it fit?

computer desk with footprint The footprint , or the physical size of a printer, determines where it can be placed. You must consider several things:

There must be a good match between the space you need to work with the printer and the spot you choose to put it! Otherwise, your print-outs may wind up puddled on the floor or you could bash your knuckles whenever you put in a stack of blank paper.


What kind of cable connection?

Serial cable (old)

Sends data only 1 bit at a time
Printer can be up to 1000 feet away from the computer.

Maximum data transfer speed = 115 kilobits/s (.115Mbits/s)

Serial cable

Parallel cable(old)

Old type: Sends data 8 bits at a time
Printer must be within 50 feet of the computer.

Maximum data transfer speed: 115 kilobytes/s (.115MBYTES/s). This is 8 times faster than the maximum serial speed.

Newer printers may need bidirectional cable so that the printer can talk back to the computer. Such a cable is required if the printer can give helpful error messages. It's startling, but nice, the first time your computer politely says "Ink is getting low" or "Please place paper in the AutoSheet feeder."

Tip Icon: WinXP Oddly, Windows XP does not support spooling for a parallel connection to a printer. Spooling is what allows you to do other things on the computer while the printer is processing and printing the document. WinXP does spool when the printer uses a USB connection.

Parallel cable
USB cable

Printer must be within 5 meters (16.5 feet) of the computer, when connecting straight to the computer.
[You can hook up several 5 m. cables and USB hubs in a chain - up to 25 meters.]

Maximum data transfer speed: 12 megabits/s (1.5 MBYTES/s) Lots faster!

Ethernet cable A printer that can be shared over a network connects to the network's router with an Ethernet cable. Ethernet cable looks a lot like a telephone cable. Installing a network printer takes more steps since you must configure it to access the network. Ethernet cable

Wireless A wireless network printer does not need a cable but it does need a strong Wi-Fi signal to connect to the network router. It does have to be configured to sign onto the wireless network, just like a tablet or phone. Wi-Fi
Best choice:

A USB (Universal Serial Bus) connection is likely your best choice. Recent printers will allow a USB connection. A USB connector can be unplugged and re-plugged without turning off the system. USB ports have replaced parallel ports. The printer cannot handle the data as fast as the USB port can send it. The real limit on how fast a printer works is in how fast printer can get the characters onto the paper.

A wireless connection can be very useful if several computers need to share a single printer. Success will depend on how good the Wi-Fi signal is.
