Question about Epson TM-L90
It sounds as if the port is trying to operate a mouse - giving the ???????. If you have windows XP then go to control panel, printers and faxes, then click "add a printer". The add printer wizard starts up, click next. select the "local printer" option and make sure the "automatically detect and install....etc" option is turned off. Click next and you should be able to select printer port. If you are using the serial port COM 1 (usually the only one externally on the pc), then select it from the list and follow the wizard through to the end. Restart the PC and you should hopefully find that the port has become dedicated to the printer alone. if still problems, go to device manager, right click on the COM 1 port and select properties, it should allow you to start the troubleshooter for the port. This should help. Other operating systems will have a similar procedure. Also worth trying is to uninstall the epson drivers, restart, plug the printer in and turn it on, and see if windows will automatically install the printer without the epson drivers. If it will, then let it do it's stuff and hopefully it will work. Hope this helps :)
