Hi every one. After installing TM88IV & Cash Drawer, using OPOS driver, Recently I have faced the following problems using Microsoft RMS 2.0 with Windows Vista.
1)when printer was connected with the cash drawer, after printing 5 or 6 receipts, POS stops responding. POS then doesn't close and everything is stuck.
2) Sometimes the cash drawer opens, but the receipt doesn't print. The computer searches for a while and then at the end it displays an error message. after restart the computer again printer & CD start working.
3) Sometimes when administrator is opened, manager and POS doesn't open.
Any ideas what might be going wrong?
Thanks
