Kay,
Well in some cases, it can be a bunch. Let's just stick with some common
hardware issues;
For instance, there are 4 ways you can talk to a printer. Text only
(printing directly to the port), OPOS, JavaPOS and Windows (at least 2 ways
within that) drivers. There is a new one that is due next year, called UPOS
USB ports on machines are relatively new. Of course, there are 2 types of
these, powered & unpowered. Plug in the wrong device into the wrong port,
poof there goes a $100-3000 device. Lets not get into the different USB
connector types, male, female, mini male, A type, B type, etc. Let's not
forget what devices you can plug into them. Printers, keyboards, mice,
modems, scanners, coffee mug heaters, personal fans, reading lights,
cameras, etc. Now should you use one port for all devices? After all, the
designers of the USB ports say that you can attach up to 256 devices to one
port. They forgot to tell us in what order to attach them. If one draws
too much power from the port, the rest downstream either don't work at all
or they only work sometimes!!
COM ports are one of the oldest way to connect peripherals, you have 5
settings there, baud rate, stop bits, data bits, parity and flow control. I
know this means nothing to you, but one wrong setting, the printer prints
gibberish. Not to mention different type of cables, with the same type of
connectors. Printer and modem cables look exactly the same, but wired
differently.
You can have 3 ways to attach a simple bar code reader. Keyboard wedge, COM
port, USB. Wrong setup in RMS or any POS frankly, it doesn't work!
Do you really want to go further with software issues? This is just a
sampling as to why this is so complicated!!

Why was the software designed to require so much "tweaking", for a month, by
a specialist in order for it to work?....Most people these days are quite
competent and quick in learning. Most retail functions and requirements are
the same: sales, orders, inventory, tags, receipts.....How many special
hardwares can there be to customize for so long?....
Microsoft has done many greater things in technology. Is this program so
complex that most people have to operate in limbo?
How muchs should the sytem eventually cost to function relatively smoothly
for a small retail operation?....The main features are impressive. The
little tricks to make it work, mainly the flaws in the interfacing, are
completely unnecessary. It wastes everyone's time and resources.....
