32 Line Matrix Printer Code V Programmer's Reference Manual

Modes of Operation

The Code V has two basic modes of operation: Normal and Graphics.

Normal Mode

In the 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.

All the standard ASCII emulation features (such as EVFU, elongated

characters, compressed print, plot mode, etc.) are still available when in

Normal Mode. However, when the Code V receives a Graphics Mode

command, the Code V changes to the Graphics Mode and assumes control of

the printer.

Graphics Mode

In the Graphics Mode, all Code V functions are available. The standard

graphics commands provide features such as underline print, horizontal and

vertical duplication, dynamic forms, graphics plotting, and vertical formatting.

A complete listing of all standard graphics commands is provided in the

“Commands” chapter.

Extended Graphics Mode

In addition to the standard graphics commands, the Code V Graphics Mode

has an extended graphics command set, providing more specific graphic

features for forms and labels. Alphanumeric commands, boxes, lines, logos,

shading, special fonts, and all bar codes are part of the extended graphics

command set.

Code V also supports the QMS Version II commands (ILOGO, IPEXP, IISO,

IBARC, IREPV, IFONT,S, IHEX, IFORM,C, IFORM,D, IFORM,E, IFORM,L,

and IFORM,R) as well as the original commands performing the same or

similar functions to those in Version II.
