Question:

In the Printer Control Sequence Description (PCSD) section of the printer driver file, can you assign a control code to each individual byte within a designated range?

Response:

The byte values referenced in the PCSD section of a printer driver file define a storage location. Four bytes are allotted for the storage of each control code. Storage starts at the beginning byte of a designated range. A control code must be entered at the first byte of that range.

For example, given the byte range 38-41, the control code for sheet feeder recognition must be entered at byte 38. The storage of this code will extend to the other bytes in the range up to byte 41. You cannot enter a code directly into byte 39, 40, or 41.
