Hi Lane We use Zebra printers. We also connect them to Jetdirect and Lantronics (1 ser, 1 par port) lan boxes. Some times we have encounted your problem. One time we just set the baud rate to 1200 to fix our problem. I think this was through a mux or Xyplex. The lan solution works really well especially if you have a parallel port on your Zerbra. They also work well on the serial or parallel port on the Lantronics device. Hope this helps.

The problem we had was that the printer did not have enough memory. We changed some labels to a larger font (so they could be read from further away), and we started having trouble with messed up labels, missed characters, etc. This problem looked to be a communication issue, but turned out to be a severe lack of memory in the printer itself. Upon ordering more memory for the printers - everything worked OK. I do not work with Zebra printers anymore (changed companies), so probably would not be of much help in diagnosing problems. > > > /~\/~\/~\/~\/~\/~\/~\/~\/~\/~\/~\ > [] Wyell Grunwald > [] Geisinger Health System > [] Information Technology > [] Mail Code 30-33 > [] 100 North Academy Avenue > [] Danville, PA 17822 > [] > [] Phone: 570-271-7342 > [] Fax: 570-271-5162 > [] E-mail: [log in to unmask] > [] Web: www.geisinger.org > \_/\_/\_/\_/\_/\_/\_/\_/\_/\_/\_/\_/ > > >>> Dave Darnell <[log in to unmask]> Monday, February 12, 2001 1:00:56 PM >>> > My experience with Zebras using software-only flow control XON/XOFF over > PVCs or other network emulation of an RS-232 hardwire is that if you still > have buffer overrun conditions, slow down the connection (at least in the > host-to-Zebra direction.
