Kick Drawer Open Command

I need a command to open my cashdrawer(Posiflex) from within my program. I use a epson u210 slip printer.

The printer and the drawer is connected with telephone type cable.

Any Suggestions

(The printer prints fine but the drawer do not open)

Shot in the (semi) dark here. The epson printers I use will kick the drawer open if you send the following control sequence:

ESC p d m n

where d is the drawer number (0 or 1) and m and n control the pulse to the drawer; I use 15 for each. So in hex, the bytes I send to open the first drawer (drawer 0) are:

0x1b 0x70 0x00 0x0f 0x0f

For this to work for you will require two things: that the printer recognize the control sequence (reasonably likely) and that the drawer be openable by the specified pulse.

It may be that in your case, a longer pulse is needed. So if it doesn't work, try making the last two 15's larger.
