With the advent of Computer Aided Drawing (CAD) programs and computer workstations, the job of draftsman changed dramatically. Before the new technology entered the workplace, everything was done by hand using an array of different tools. After CAD was introduced, all of these tools became obsolete curiosities. All that was needed to create an engineering drawing was a computer terminal and an engineering plotter printer.

Before CAD, drawings were, in fact, drawn rather than printed. The draftsman applied pencil or, in most cases, pen to paper and drew. To make straight lines, the draftsman used a T-Square which slid up and down along the edge of the drawing table. If they needed a vertical line, then they could place a triangle against the T-square as a guide. Later, drafting machines were invented and allowed vertical , horizontal and angled lines to be drawn using a system of pulleys to keep the instrument parallel to the bottom edge of the drawing surface.

Straight lines were easy. To draw curved lines and circles, however, you needed even more tools. Circles were drawn using a compass for larger circles or a circle template for smaller circles. Circle templates were simple pieces of plastic with round holes cut out of them in a variety of sizes. The draftsman would put his pen or pencil on the inside edge of the circle and trace it. A compass held the pen on one leg and a metal point on the other leg. The compass was adjusted to match the radius of the desired circle and the sharp point was place at the desired center point of the circle. The leg with the pen or pencil was then swung around the center point until a full circle had been drawn, usually leaving a small hole at the center point.

If one needed to draw a curve that wasn’t precisely circular, then the dreaded French curves were brought to bear. A French curve was another piece of flat plastic that was carved in such a way that its edges presented a wide variety of different curves. The draftsman would plot on his paper a number of points along the curve required for the drawing and then slide the French curve around until one of its curves touched all of the plotted points and described the desired curve. If the curve was particularly complex, this process might be repeated multiple times for different parts of the curve.

No line was ever drawn freehand on a technical engineering drawing. Freehand was fine for original concept sketches, but could never be trusted to draw the precise curve or perfectly straight line called for on the drawing.

All of that changed when CAD was introduced. CAD made drafting easier, by automatically making lines straight or curved precisely as desired. Snap grids made every line perfect. When a paper copy of the drawing was needed, the file was sent electronically to the large size plotter printer and a paper copy was printed out.

If you have worked in an office within the past couple of decades, you have probably encountered some type of thermal paper. The most common form of thermal paper that comes to mind is the older style of fax machine paper. Probably everybody remembers those long rolls of slick paper that many fax machines used; this was most likely thermal paper.

But why is this paper called, Thermal Paper, and how does it work? Thermal paper is a specialized form of paper that contains a chemical that is sensitive to heat. This type of paper, when used in a compatible printer, will produce a document by being exposed to heat. Typically the chemical used on the paper will produce black text, but sometimes chemicals that will produce blue or red text are used as well. Some thermal paper also have a protective top coating that may protect the printed material from fading, which can happen when the printed material is exposed to ultraviolet light, water, or certain oils. This protective top coating may also improve the functioning of the thermal printer itself.

Thermal printing is different from other types of printing because this type of printing does not require the use of any type of ink. This can be very convenient, especially when you think of the high cost of many printer’s ink cartridges and the hassle of discovering that your printer is out of ink just as you are ready to print an important document.

Because thermal printers and thermal papers do not require ink, many commercial business segments find the thermal printing option to be very appealing. While the outdated fax machine paper may be the first thing that comes to mind when you think of thermal paper, there are actually many applications for thermal printing and thermal paper that are still in very wide use today. Many of the receipts you receive today are printed on thermal paper. This includes retail store receipts, grocery store receipts, restaurant receipts, automated gasoline station pump receipts, and automated teller machine (ATM) receipts, plus many others.

Using a printer that uses thermal paper rolls can be a smart choice for customer service oriented businesses because not only is it cost effective due to the lack of ink usage, but it can make printing receipts and such a much more user friendly process. How many times have you been stuck waiting in line to pay for your goods or services because a cashier is fumbling around trying to change think ink ribbon on a receipt printer? With a thermal printer this is obviously not a concern because you will never run out of ink if ink is not used!

Thermal paper rolls are also readily available, so business consumers do not have to worry about access to this specialized type of paper. Many office supply stores and online retailers sell a wide variety of thermal paper rolls. If your business uses a lot of thermal paper rolls, it would be wise to contact your online retailer for bulk pricing discounts.
