Printronix SL5000r MP PGL EPC Format Handling Selected Size of Data Based on, Length Program

Chapter 3 64 Bit And 96 Bit EPC Data Formats

IMPORTANT When any of these three parameters are inconsistent then confusion is likely.

The following tables (Table 5 on page 74 for PGL and Table 6 on page 75 for ZGL) identify the consequences of mismatched criteria.

Table 5. PGL EPC Format Handling

EPC Format	Selected	Size of Data

header)	Length	program)
64 bit	64 bit	< 64 bit	OK	Pad 0s to left for 64 bit
64 bit	64 bit	= 64 bit	OK	As is
64 bit	64 bit	> 64 bit	Error	Data too long
64 bit	96 bit	< 64 bit	Read 96 bit	Pad 0s to left for 96 bit
