That sounds similar to a "situation" I encountered a few years ago while
working with Zebra Bar Code printers.  I created a batch file to read a list
of part numbers.  One bar code label for each part number.  My memory can't
recall the exact number of labels, but the batch job would "lock up" at some
number of part numbers printed, let's say 800.
My work-around was to make a counter variable and stop printing at 750
labels.  Stop the program, then restart from label #751.  I assume that by
restarting, a memory buffer was cleared.  I didn't have time to figure out
why, but the workaround got the job done that's always needed yesterday!
Good Luck!

Hello gents -

I believe I've tried everything under the sun to fix
this problem - to no avail.

I have a slew of Zebra stripe label printers (serial)
and I'm driving them with a DTC 16/MX.

The DTC config is straightforward - printer type 18,
baud was 19200, now I've stepped it down to 9600.  The
flow control on the printers is set appropriately to
XON-XOFF.

Basically, what happens is the printer will just stop
in the middle of a print job - the data light stays on
- the 3K shows the file active.  Not every job - it
actually is very random.  It's not file size related
as it happens with small files, or very large files.
Not cable issues (cat 5 tested end to end).

Any help/ideas would be greatly appreciated.

PFG
