The standard line spacing is the only one you need for almost all printing of text, but in some cases you may want to increase or decrease the space between lines. The LX-90 has several commands to do this. ESCape "0" changes the line spacing to l/&inch, ESCape "1" changes the line spacing to 7/72-inch, and ESCape "2" returns it to l/6-inch. In addition there are commands to specify the line spacing in 72nds of an inch and 216ths of an inch. If you need to make such fine adjustments in the line spacing, see Appendix C for the proper commands. In the chapter on dot graphics you will see how useful changes in line spacing can be. Paper-Out Sensor Under the platen (the black roller) of your LX-90 printer is a small switch that senses whether or not paper is in the printer. When the end of the paper passes this switch, it triggers a signal that sounds the beeper and stops your printing. This saves wear on your print head, ribbon, and platen, but because of the distance between the switch and the print head, it stops the printing about 2 inches from the end of the page. Therefore, if you use single-sheet paper in your LX-90, you can't print on the last two inches of each page without an adjustment. If you need to print on the last two inches of single sheet paper, there are two solutions: send the printer an ESCape "8" or change one of the DIP switches described in Appendix D. Then the printer will ignore the paper-out signal. This will allow you to print on the last part of each page, but be careful not to allow the LX-90 to print without any paper in it. Justification with NLQ The NLQ (Near Letter Quality) mode offers a justification command that gives you four choices in the formatting of your text. The command is ESCape "a" followed by one of these numbers: 0 Left justify 1 Center 2 Right justify 3 Auto justify Left justification is the standard format, in which the left margin is even and the right margin is not. This is the way most typewritten pages look. 37

Paper-Out Sensor
Under the platen (the black roller) of your LX-90 printer is a small
switch that senses whether or not paper is in the printer. When the end
of the paper passes this switch, it triggers a signal that sounds the
beeper and stops your printing. This saves wear on your print head,
ribbon, and platen, but because of the distance between the switch
and the print head, it stops the printing about 2 inches from the end of
the page. Therefore, if you use single-sheet paper in your LX-90, you
can’t print on the last two inches of each page without an adjustment.
If you need to print on the last two inches of single sheet paper, there
are two solutions: send the printer an ESCape “8” or change one of the
DIP switches described in Appendix D. Then the printer will ignore
the paper-out signal. This will allow you to print on the last part of
each page, but be careful not to allow the LX-90 to print without any
paper in it.
Justification with NLQ
The NLQ (Near Letter Quality) mode offers a justification com-
mand that gives you four choices in the formatting of your text. The
command is ESCape “a” followed by one of these numbers:
0 Left justify
1 Center
2 Right justify
3 Auto justify
Left justification is the standard format, in which the left margin is
even and the right margin is not. This is the way most typewritten
pages look.
