Switch 1-1--In the down position, this switch allows you to create a buffer of 2048 bytes of memory. This buffer can be useful when you want to print a document at the same time you continue to use your computer for other tasks.

WARNING: If you turn OFF the LQ-1500, any information in the buffer is lost.

Switch 1-2--Switch 1-2 enables a detector in the LQ-1500 that warns you when the printer is out of paper. This is very important when you are using continuous paper. The printer stops, issues an audible warn- ing, and waits for you to load more paper before proceeding-and no data is lost.

However, if you are using single sheets, the paper-out detector stops the printer when it nears the bottom of the sheet (even if you want to print all the way to the bottom or if you have another sheet ready to feed). In this case, it is best to disable the paper-out detector by turning switch 1-2to the Up position. With the printer’s paper-out detector disabled, the application software in your computer must determine when it has come to the end of a page. Check with your software dealer if you have difficulty.

Switch 1-3--Switch 1-3 controls whether or not the LQ-1500 does an automatic line feed each time it receives a carriage return. Some computers do not send line feeds to the printer which means that this switch must be up.

Switch 2

Switch 2 determines which print characteristics will be in use when the LQ-1500is turned on. Each of these functions can be changed at
