Further developments - We've had another "incident", this time without
2GB fix, and with the revised implemention that uses PRINT FILE to a
buffer: When COPYing the buffer file to LPT3, only the first part of
the file goes to the (network) printer. The rest is lost, and the
print queue is empty.

At the time of the failure, I was able to duplicate this behavior from
a command line using COPY BufferFile LPT3 /B, with XP reporting "1 file
copied". However, COPYing the same file directly to the printer's UNC
name works fine! I've re-tested each way with 100% consistency.

So, the problem seems to be with the NET USE connection between the
local LPT3 port and the network printer. And whatever is causing that
file loss was presumably triggering the "Not Enough Memory" error with
the previous PRINT FILE LPT3 implementation.

Anyway, COPY to the unc seems to resolve the problem. Although the
(intermitent) NET USE failure mystery remains.

that's the only way I know of to do this on XP.. glad you finally came on
board (g)

Steve,

I think you missed my point: This problem and its resolution had
nothing to do with COPYing a buffer file vs a direct PRINT FILE.
Although one may be better than the other in some regards, they are
both functional.

The root problem here is that the virtual LPTx port created by NET USE
is buggy. The problem occurs if I COPY -or- PRINT FILE to the LPT
port, but not if I use the UNC name.

Peter

we never said that PRINT FILE was your problem.. we suggested te
possibility, on XP, because it's not the way the rest of us do things,
because of related issues that we've found in XP.. "different" is always a
possible problem, until proven otherwise (g)


to which I replied "I absolutely agree".. on XP machines, I only use the
UNC..
