PS/2 External Keyboard Port

The state of the art in large robotic prescription filling machines (start with an empty vial and finish with a labeled vial with the required pills in it) is such that it is not economically justifiable to use them in most retail pharmacies, and even when they are used a 200 cell unit will only aid in dispensing between 50% and 67% of scripts that can be filled by tablet counting.  A 100 cell robot will do about 2/3 as many scripts because the drugs are usually picked on a usage basis. Not a negligible feat, but far from complete automation.
In the end, all pharmacies must face doing the script filling completely manually or adding some forms of pharmacy automation to help relieve the physical burden or save time and money.  There are many forms of automation and all pharmacies have some form of PMS (Pharmacy Management System) to help with the large clerical burden, and most of these are capable of generating the label packet required for filling a script.
