32 Line Matrix Printer Code V Programmer's Reference Manual

Data Positioning

Normal Mode

In Code V Normal Mode, incoming data are checked by Code V software for

the SFCC and the Graphics Mode Enable or the Enable Non-Graphics Free

Format command, then passed to standard printer software. These "normal"

(or "pass-through") data assume the standard 10 cpi print mode, and all other

standard printer features function normally according to the configuration and

programming of the printer.

NOTE: Printers must be configured at the control panel for Data Processing

10 cpi (DP 10) print mode at 6 lpi for the Code V to operate properly.

To set a line spacing when Code V is active, use the Line Spacing

(@L) command described on page 95.

Graphics Mode

Some graphics commands have different functions depending on whether the

command is used within an extended or a standard graphics command

sequence. For example, the W command identifies a standard graphics

command line slew; when used within an extended graphics command

sequence, W identifies a Character Width Change command. Therefore, be

certain of appropriate command usage to obtain the desired results.

Data Positioning

In the Graphics Mode, you must understand certain positioning rules to obtain

the desired results. Horizontal and vertical starting positions of a command

are determined either by implied relative position to the prior graphics

command or explicit position from a positioning command.

Implied Relative Positioning

For any graphics command sequence (a string of one or more extended

graphics commands), the initial “relative” print position is the current dot row

and column 1 or the Graphics margin, if set.

NOTE: Because previous command sequences may have been used to

define prior printing on the page, the actual physical position of the

print mechanism may be on a different row, but it will always be in

column 1 or the Graphics margin, if set.

Without an immediately preceding positioning command, the starting position

of any command within the sequence is dot row 1 and the first dot column

past the right edge of the previous command “print envelope.” This implied

position may be modified horizontally or vertically by specific positioning

commands.

Without explicit horizontal positioning commands, the horizontal print position

constantly increases within the command sequence. Each command starts at

the right edge of the previous command. Without explicit vertical positioning

commands, the vertical print position for each command within a sequence is

always at relative dot row 1 (the current physical position of the print

mechanism resulting from printing the last sequence).
