There are several important things to consider when selecting a place to set up your printer. Keep the following in mind: Place the printer on a flat, hard, stable surface. A soft surface, such as a padded counter or carpeted area, will block the ventilation slots and may cause overheating. Place - Epson LQ-950 | User Manual - Page 23

you've decided on the best place to set up your printer, the next step is to install the platen knob. Installing the Platen Knob You use the platen knob to feed the paper manually in the event of a paper jam or other paper feeding problem. The platen knob is packed in an indentation in the - Epson LQ-950 | User Manual - Page 25
knob to adjust the . position of the paper. This interferes with the automatic paper loading system and may cause a paper jam. Installing the Ribbon Cartridge Your printer's ribbon cartridges are designed for easy installation and removal. You install the standard ribbon cartridge and the optional - Epson LQ-950 | User Manual - Page 26
this can damage the printer. Also, if you have been using the printer, the print head may be hot; let it cool for a few minutes before touching it. 4. Turn the ribbon-tightening knob in the direction of the arrow. This removes slack in the ribbon and makes it easier to install. 1-12 Setting Up the - Epson LQ-950 | User Manual - Page 27

, the paper guide helps to feed the paper smoothly and efficiently into the printer. Attach the paper guide using the following procedure. 1. Place the paper guide on the printer as shown below. Make sure the back edge of the guide is even with the back of the printer. Setting Up the Printer 1-15 - Epson LQ-950 | User Manual - Page 30
2. Raise the paper guide until it locks into place. Note: To lower the paper guide, lift up slightly to release it from its locked position; then gently lower it down onto the printer. 1-16 Setting Up the Printer - Epson LQ-950 | User Manual - Page 31

If you use commercial software that produces graphics, all you need to know about dot graphics is how to use - Epson LQ-950 | User Manual - Page 130
know a little about how your printer's print head works. The print head has 24 pins. As the print head moves across the page, electrical impulses cause the pins to fire. Each time a pin fires, it strikes the inked ribbon and presses it against the paper producing a small dot. As the print head moves - Epson LQ-950 | User Manual - Page 131
up to 180 dots per inch, horizontally. As the print head moves across the paper, every 1/180th of an inch it must receive instructions about which of its 24 pins to fire. At each position it can fire any number of pins, from none to 24. This means that the printer must receive 24 - Epson LQ-950 | User Manual - Page 132
Pin labels To tell the printer which pins to fire in each column, you first divide each of the vertical system is shown below: 126 64 32 16 : 2 1 To fire any one pin, you send its number to the printer. To fire more than one pin at the same time, add up the numbers of the pins and send the total. - Epson LQ-950 | User Manual - Page 133

The printer interprets the number of bytes specified by nl and n2 as graphics data, no matter what that you must be sure to supply enough bytes of graphics data or the printer will stop and wait for more data and will seem to be locked. If - Epson LQ-950 | User Manual - Page 136
image. While this method is the most tedious, it helps you understand dot graphics. It is also useful for small graphic elements that are used an inch wide. The actual pattern that the printer prints on the paper is, of course, made up of dots that overlap each other both vertically and horizontally - Epson LQ-950 | User Manual - Page 137
Write the assigned values of the pins next to your design, then total the values for each column of dots. These totals are the values that you send to the printer as graphics data to print the design. Below is the same grid divided into three sections to make the data calculation easier - Epson LQ-950 | User Manual - Page 138

In fact, planning a user-defined character is - Epson LQ-950 | User Manual - Page 142

For draft characters, the grid is nine dots wide, for Letter Quality it is 29 dots letters except those with descenders (the bottom parts of such letters as j and y). The - Epson LQ-950 | User Manual - Page 143
This means that there must be an empty dot position both to the left and right of each dot that prints. This is true in draft, printer. Every dot has an assigned value. Each vertical column (which has a maximum of 24 dots) is first divided into three groups of eight dots. Each group of eight dots - Epson LQ-950 | User Manual - Page 144
byte is calculated by adding the values of the rows in which dots appear. The right side of the figure shows the whole character with This manual uses decimal numbers because the program examples are written in BASIC and everyone is familiar with decimals. The data you send to your printer, however - Epson LQ-950 | User Manual - Page 145
