DEC LA120 Emulation

Character Size

The FormsMaster 8000 series printers are capable of supporting 10, 12, 13.3, 15, 16.7, 17.14, and 20 cpi, but most emulations support only a subset of these. LA120 emulation supports 10, 12, 13.3, and

16.7cpi via software, but does not support 15, 17.14, or 20 cpi. Every emulation supports 10 cpi, and we consider this to be the default character pitch. When you use the control panel to change the “Characters/Inch” value in the forms menu, you are actually changing the default character pitch. When the printer is turned on (or reset), it will use this character pitch. You can even use a pitch that is not supported by your emulation, such as 15 cpi with LA120 emulation. You can override this pitch selection via software, by sending an escape sequence. This selects a user specified non-default pitch. For example, in LA120 emulation, sending ESC [2w will select 12 cpi. Sending ESC [w will re-select 10 cpi, and thus re-select the default character pitch that was selected in the form setup.

Via software escape sequences, you can select any character pitch supported by the emulation you are using. All will print as expected, unless you select 10 cpi -- because 10 cpi really selects the default character pitch from setup. If you really want 10 cpi, then you must set “Characters/Inch” to “10” in the forms menu. Likewise, if you want to use the default pitch from setup, you must not override it. Either send no character pitch sequences to the printer, or make sure you re-select 10 cpi via software.

When you select different forms, the default character pitch from setup is selected along with the form. But you will not see this default pitch if it has already been overridden via software.

Set Character Spacing ESC [ n w

Sets the character spacing as specified in the following table. Omitting n is equivalent to specifying zero.

Overrides the “Characters/Inch” value in the forms menu.

Example: The following escape sequence will select 10 cpi character spacing. If “Characters/Inch” was not set to “10” in the forms menu, the specified default character pitch will be selected instead of 10 cpi.

Example: The following escape sequence will select 12 cpi character spacing.
