LPT1 timeout dos printing
We run Dac Easy for our Point of Sale. It will only print to LPT1 for
receipts. So I have the physical LPT1 disabled and lpt1 mapped to a shared printer on the server. Worked great for 2 years with the printer on the only domain controller with 2003SP1. We put in a second domain controller with 2003 R2 which was set as the primary. While old DC was secondary, with the printer still being shared on the old DC, we can open Point of Sale and print a few receipts no problem. if we then leave POS up and come back in 20 minutes we get an error saying it cannot find the printer and a remote downlevel document is stuck in the queue. If we close the POS app and restart it the Remote Downlevel document clears and everything works fine till the next time we wait 10-20 minutes before the next receipt. This is happening on all 14 workstations. Things I have tried: 1. Deleteing the printer from server and workstations and reinstalling it on another server. 2. Setting the printer timeout and power saver to 1 hour. 3. Getting updated windows drivers even though the POS is using DOS printing. Since i think this has to do with the upgrade to the R2 schema, what in there could possibly effect this? |
