Using the
Pattern
Processor
The pattern processor enables the TROY printer firmware to search the incoming print data stream for a specified
string(s) of characters and then substitute the matching data string(s) with an alternate user-defined data string(s),
allowing a PCL (Printer Command Language)-based printer to accept an otherwise non-compatible print job
(e.g., line feed-based print jobs generated by a mainframe computer) for printing check jobs.
When enabled via the TROY Printer Utility, the pattern processor accumulates data from the incoming print job,
temporarily storing the data in a memory buffer in the TROY DIMM/flash memory card for processing. When
enabled, the pattern processor incurs processing overhead; therefore, the pattern processor should remain disabled
when not in use to avoid unnecessary slowing of the printing process.
Each character string(s) is matched in turn against the input data accumulated in each successive memory buffer.
If there is a match, then the user-defined substitution pattern is used to create a new buffer that is integrated into
the print data stream. Refer to the
TROY Programmer’s Reference Guide
(included as a PDF file on the
TROY
Security Printing Solutions
CD) for detailed information and programming examples.
