Horizontal Margin Selection

Horizontal Margin Selection

Horizontal Margin Selection

Absolute left and right margin selection is accomplished using the following escape sequences:

ESC&a[print position]L Set left margin

ESC&a[print position]M Set right margin

The print position specified indicates a decimal number in the range 0 through

131@ 10cpi (0 - 65 for Double-size, 5 cpi, 0-219 for compressed, 16.67 cpi). The print position represents the column using the print pitch active when the margin is set. For example, if the character pitch is 10 characters/inch and the left margin is set to column 20, the left margin will be two inches from the left physical limit of the printer. If the pitch is then changed to 5 characters/inch, the left margin would still be in the same logical position, but column 20 would be four inches from the left physical limit of the printer instead of 2 inches.

Margins can be set at any column, regardless of the present printing position. If the new margin selected is to the right of the current print position, then the new setting takes effect immediately. If the new margin setting is to the left of the current print position, then the new setting does not take effect until the cursor is reset to zero.

The first column within a line is designated column 0. If a print position greater (or less) than the printer’s physical limit is specified, the right (or left) margin will be set to the limits of the printer. Power-on and set the margins to the maximum limits.

Commands are ignored if the result would place the left margin to the right of the right margin. The only way to move the current active position outside the margins is by using the escape sequences for horizontal cursor control.

To release the right margin use one of the following escape sequences:

ESC&a132M for 10 cpi

ESC&a158M for 12 cpi

ESC&a175M for 13.3 cpi

ESC&a198M for 15 cpi

ESC&a220M for 16.7 cpi

Transparent Print Data

This feature allows the printing of binary data which is required in certain applications. The escape sequence ESC&p[# of bytes]X enables the printer to print data as in the display functions mode, except that no control codes or escape sequences (including CR and ESCZ) are executed. The number specified in the value field is the exact number of bytes that will be interpreted as binary.
