IBM Proprinter Emulation
Character Size
The FormsPro 4000 is capable of supporting 10, 12, 13.3, 15, 16.7, 17.14, and 20 cpi, but most emulations support only a subset of these. IBM Proprinter emulation supports 10, 12, 17.14, and 20 cpi via software, but does not support 13.3, 15 or 16.7 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 "CPI:" value in the "Setup: FORM" 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 13.3 cpi with IBM Proprinter emulation. You can override this pitch selection via software, by sending an escape sequence. This selects a user specified
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
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.
Select 10 CPI | DC2 |
Selects 10 cpi by cancelling 12 cpi and condensed mode. If "CPI: 10" was not
specified in the "Setup: FORM" menu, the specified default character pitch will be selected instead of 10 cpi.
Control code: | DC2 |
Hexadecimal: | 12 |
Select 12 CPI | ESC : |
Selects 12 cpi (elite mode). Condensed mode is unaffected. The resulting character spacing will be 12 cpi, or if condensed mode is also selected, 20 cpi.
Escape Sequence: | ESC | : |
Hexadecimal: | 1B | 3A |
