Chapter 5 IPDS Programming Information 115 260071 ‐ 001A
Chapter 5. IPDS Programming Information
This chapter contains programming information for the Intelligent Printer Data Stream (IPDS) commands.
The information is for the experienced programmer. A knowledge of data stream requirements, hexadecimal
numbering systems, and data processing terminology and concepts is assumed.
In addition to the information in this chapter, Chapter 4, “Intelligent Printer Commands,” contains introductory
information about the IPDS.
IPDS Initialization Defaults
When the printer power switch is initially turned On (|), various IPDS data stream parameters are set to
their initialization default values. These values remain in effect until overridden by specific data stream
commands from the host application program.
Table 6 contains the initialization defaults for this printer:
Table 6. IPDS Initialization Defaults
Default Description Hex Value
Units Base Value 00 (10 in.)
Input Media Source Determined by Operator Panel Paper Source setting
Width of the Physical Medium MPP Value, Operator Panel Selection
Length of the Physical Medium MPL Value, Operator Panel Selection
Width of the Logical Page in Units (X-Extent) 4A40 (Decimal 13.2 in. Width, 1440 Units Per In.)
Length of the Logical Page in Units (Y-Extent) 3DE0 (Decimal 11 in. Length, 1440 Units Per In.)
Ordered Data Flags 00 (Unordered Page, Block, and Text Flags)
X-Axis Orientation 0000 (0 Degrees)
Y-Axis Orientation 2D00 (90 Degrees)
Current I Text Position 0000
Current B Text Position 00A0 The Default Font Type Baseline (see Note 1)
X-Displacement 0000 Logical Page X-Displacement from Physical Medium Origin
Y-Displacement 0000 Logical Page Y-Displacement from Physical Medium Origin
Initial Inline Margin in Units 0000
Intercharacter Adjustment 0000
Baseline Increment LPI value, Operator Panel Selection
Local Font ID FF (see Note 3)
Text Color Black
Code Page ID Language value, Operator Panel selection
Font Quality Print Quality value, Operator Panel selection
Font Type Determined by Print Quality and CPI value Operator Panel
selection (see Note 2)
Exception Handling Control Report Undefined Characters, Position Checks, and All
Other Exceptions. Do Not Take Alternate Exception Action.
Terminate, Print Page, and Go to Home State.
Notes:
1. Text printing on the first line requires an initial Y-displacement value of 00A0.
2. The printer default font is Gothic for DP and fast draft print quality and Courier for DP Text and NLQ
print quality. To determine the current values for CPI, language and quality, refer to the Administrators
Manual for your printer.
3. When Local Font ID equals FF is used, the latest inline sequence established in “Logical Page
Descriptor (LPD)” determines whether to print in a left-to-right or right-to-left sequence. The default
when the printer is powered on is the left-to-right sequence.
