Chapter 2 The IPDS Emulation

Exception Processing and IDs

Unlike some other protocols, IPDS allows the host to control exception (error)

processing, which can free up the printer cpu.

The host can request one of two methods:

• the printer must print the pages as requested

• the printer does not allow any page that has a data stream error to print

The first method applies for situations such as printing checks; the second

method applies for printing drafts or when troubleshooting the data streams.

The following tables list the exception IDs and the error conditions. The

exception ID consists of three parts. For example:

8001..00

80 = sense byte 0, which indicates a command reject

00 = sense byte 1

00 = sense byte 2

Table 8. Exceptions: Rejected Comands

Exception ID Condition

800100 Invalid IPDS command code

800200 Invalid IPDS command sequence

80E000 Invalid IPDS command length

Table 9. Exceptions: Data Check

Exception ID Condition

082100 Undefined character

086000 Numeric representation precision check

08C100 Position check
