Glossary Print quality The LQ has two types of print quality: draft and Letter Quality. Draft is for high-speed, draft quality jobs; Letter Quality is for final, polished correspondence. Proportional printing Printing in which the width of the character varies from character to character. Therefore, a capital W, for example, receives much more space than a lowercase i. RAM Random Access Memory. The portion of the printers memory used as a buffer and for storing user-defined characters. All data stored in RAM is lost when the printer is turned off. Reset Returning a printer to its defaults, with either a command, an INIT signal, or by turning the printer off and on. Self test A method of checking the operation of the printer. When the self test is turned on, the printer prints the characters that are stored in its ROM. Serial interface An interface is the connection between the computer and the printer. There are two types: a serial interface transmits data one bit at a time, and a parallel interface transmits data one character or code at a time. Short tear-off A feature that automatically feeds the perforation of continuous paper to the tear-off position and then feeds the paper back to the loading position. This position can be adjusted with the micro-adjustment feature. See Micro adjustment. 10 pitch A pitch with 10 characters per inch. This is often the standard or default character width. GL-6
