Cash Drawer not opening

[Jezzrel]

We have a pos printer connected to a cash drawer, it works fine for a year until it prints abnormally (paper not feeding properly thus receipts are not printed before it cut).

We replace with a different brand of pos printer, printing of receipts are ok but it would not open the cash drawer.
I suspect that the control codes is different, I wanted to try to change the control code but I cannot find where to change from the ESCPOS source code.
Can you point me which source file to amend?

Thank you.

Hi, have a look here:

perl-Printer-ESCPOS/lib/Printer/ESCPOS/Profiles/Generic.pm

Line 1138 in 5ef7fc0

$self->driver->write( _DLE . _DC4 . "\x01" . chr( $pin ) . chr( $time ) );

Hi,

Is below the code for the control code?

$self->driver->write( _DLE . _DC4 . "\x01" . chr( $pin ) . chr( $time ) );
If my printer control code to open a cash drawer is 27.112.0.25.250, how can I put on the above code?

This should probably done by

$self->driver->write( _DLE . _DC4 . join("", map { chr } qw( 27 112 0 25 250 )) . chr( $pin ) . chr( $time ) );

(untested, please try for yourself)
