we have a brand new samsung srp-350 receipt printer and a mmf value-line cash drawer. The printer is connected via lpt1 and the cash drawer is connected to the printer. i am having trouble getting the drawer to pop open even with the proper drawer pop codes it would seem. im wondering if the cable i have (which is a 6 pin to 6 pin straight through epson cable) is the proper cable for this configuration... as i can get no results with this combination of hardware. perhaps someone has a similar setup (by the way the software in use is comcash POS, but i cannot get the thing to pop from vb or the command line or via the after print commands in the advanced portion of the printer driver). any insight on this particular setup would be greatly appreciated.
i have measured voltages accross the pins on the cable itself... pin4 is +24v and according to further research ... when the proper codes are sent to the printer you should be able to measure a +24v pulse accross pin 2 and 4.. i am able to measure this change so i know the pop codes are correct... i suspect a cable pinout issue... please help if you can!
