never need to set them with the control panel.

Default settings descriptions

Character spacing

When you select 10 cpi, the printer prints 10 characters per
inch (cpi). When you select 12 cpi, it prints 12 characters per
inch.

Shape of zero

The printer prints the zero character with a slash (0/) when
the setting is on, or no slash when the setting is off. The
slashed zero makes it easy to distinguish between an
uppercase O and a zero.

When this feature is on and you are using continuous paper,
the printer leaves a 1-inch (25.4-mm) margin between the last
printable line on one page and the first printable line on the
next page. This causes the printer to skip over the perforation
between continuous sheets.

Most software takes care of the top and bottom margins. Do
not turn on skip-over-perforation unless your software does
not provide these margins.
