My understanding from once long ago having stared over a
sysprog's shoulder is that the information goes into the spool
loss-free, with each spool record consisting of:
o A flag indicating carriage control type (A, M, or none)
o The carriage control character.
o The body of the record.
(I vaguely recall that long ago there was a problem of
losing trailing blanks. I believe that was necessarily
fixed to support bitmap graphics for AFP.)
I'm inclined to blame either the writer (is that VPS?) that
extracts the file from the spool, or the printer driver.
If either ignores or discards the flag that indicates
"no carriage control", then processes the carriage control
character (which it then _should_ ignore) as ASA carriage
control, the problem is created.
