SNA*ps Print emulates an IBM 3287 or 3812 printer which supports LU3 (3270
data streams) or LU1 (SCS data streams) only. AS/400 printing is done only
with LU1. The emulation is expecting to decode data (text only) within one
of the mentioned data stream formats.
Therefore, SNA*ps Print is not a solution for printing Host based
Postscript documents.
