DuplexModes

DuplexModes is a public enumeration defining the controlled vocabulary for duplex printing modes used by clsXPrintControl.DuplexMode. Each member maps to a fixed 5-character database code stored in XPRINT_CONTROL.DUPLEX_CODE and related columns. See BR-004.

Purpose

• Provide a type-safe vocabulary for duplex printing mode selection.
• Translated to/from fixed database codes by clsXPrintControl.DuplexMode.

Context

• Namespace: SAIF.Services.Printing.Remote
• Assembly/package: SAIF.BOF.Services.Printing.Remote
• Defined in: Enums.vb

Public members

Member	Signature	Purpose
SIMPLEX	SIMPLEX = 0	Single-sided printing; maps to database code SIMPL. Default enum value (ordinal 0).
VERTICAL	VERTICAL	Vertical duplex printing; maps to database code VERTL.
HORIZONTAL	HORIZONTAL	Horizontal duplex printing; maps to database code HORIZ.
DEFLT	DEFLT	Default system duplex setting; maps to database code DEFLT.

Behavioral notes

• clsXPrintControl.DuplexMode getter maps the stored 5-character code to the enum value; unrecognized codes fall through Select Case with no explicit Return, implicitly yielding SIMPLEX (ordinal 0).**
• The setter maps the enum value to the 5-character code for DuplexCode storage.
• The same 5-character codes appear in XDOCUMENT.DUPLEX_CODE and XDEFERRED_PRINT.DUPLEX_CODE, but those columns are stored as raw strings without explicit translation in their respective classes.*

Constraints and usage notes

• Only the four defined members have reliable round-trip storage; any other code stored in the database will not map to a named member.**
• All four valid codes are exactly 5 characters (SIMPL, VERTL, HORIZ, DEFLT).

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
