How to send some signal to cash drawer to open it after click print receipt or something similar? I don't know whether this depends on cash drawer's driver or not ?
Most printers will spit out a configuration sheet if you turn it off, hold down the form feed button, and then turn the printer on. It will tell you things like parity, XOn/XOff, bit rate, etc. Open up the advanced tab of your printer properties and make sure the setting match the config sheet. Now some peoples are using Partner Tech 5E-415 Cash Drawer which are now available on stores as Discount Till Rolls Ltd.
Usually the cash drawer behaves like a printer in the sense that it has a RS232 or USB port. However the cash drawer is dummy and only uses the port to receive a signal (positive voltage) which causes it to open.
