The module is developed for patient registration, and is able to create new patients including recording of relevant demographics and a standard national address hierarchy, identify previous patients, create barcode with unique ID, scan barcode, record patient vital signs, scan national ID and record which service the patient is attending.
The patient registration runs as a touch screen application. The module uses Baobab Touchscreen Toolkit to simplify the development of touch-friendly user interfaces without requiring each page to be individually and consistently customized for touchscreens. See http://github.com/baobab/touchscreentoolkit.
The touch-screen computers will be configured to start OpenMRS using this form .../openmrs/module/rwandaprimarycare/login/login.form
--the Rwanda location code is expected to be the three-digit code assigned to each health center by the Rwanda Ministry of Health. For example, the three-digit code for Rwinkwavu Health Center is 416. The primaryIdentifierType should be the identifier type that you just created for primary care registration IDs. If there is the possibility of receiving transfer patients from other health centers where they may have received a barcode, setup the global property: registration.rwandaLocationCodes. These are pipe delimited pairs of Health Centers by name, and Health Center MoH three-digit location code. For example, a valid entry would be "Rwinkwavu Health Center:416|Kirehe Health Center:477|Rusumo Health Center|412". (please verify your location codes before going live).
registration.parentChildRelationshipTypeId). If this global property is empty, check the database to determine the ID of the parent to child relationship type (or create one).

(Note: this section already assumes that you have installed Ubuntu on your touchscreen, and that the touchscreen drivers are working correctly. These do not have to be powerful machines in the least -- all the touchscreen has to do is run Firefox or Chrome. In Rwinkwavu, we're using J2 touchscreens, which are heavy-duty, and suitable for outdoor use.)
1) Configure Firefox for the touchscreen user:
2) Lock-down Ubuntu into a Firefox kiosk
3) Configure automatic login
4) setup barcode printer. In Rinkwavu, we're using the Zebra TLP2844 (NOT the LP2844, and NOT the TLP2844-z), with ELP2 support.
Plug the printer into USB port
Create a two-line file barcodeprint.sh:
cat $1 > /dev/usb/lp0
When Firefox asks which program to open barCode.epl with, pick barcodeprint.sh
In order for this to work, you must add the linux user to the lp group.
Finally, in the current builds of Firefox, the 'remember my selection and do this from now on' checkbox that SHOULD remember that you want to open the .epl file with barcodeprint.sh doesn't currently work. The firefox plugin Web Page Fixer can be used to fix this. This plug-in is available here: https://addons.mozilla.org/en-US/firefox/addon/10422/.
5) configure scanner for pdf417, and code128
need to download the manual and print relevant configuration codes; maybe we can make the beep less obnoxious
6) interfaces file needs:
iface eth0 inet dhcp
(this also seems to work??):
iface lo inet loopback
7) it is also recommended that once a firefox profile is established that works correctly in touchscreen mode, and prints barcodes correctly, that a tar file is created of the firefox profile, and that this tar file overwrites the existing firefox profile at startup. We have seen several instances where the barcode file that is downloaded becomes linked to the wrong application, or the firefox homepage gets reset to something other than the touchscreen interface page in OpenMRS. By restoring the firefox profile at startup, these errors can be fixed with a simple reboot.
to create your tar file:
1. go to touchscreen <<user's home directory>>/.mozilla/firefox
2. read the profiles.ini file to determine the profile folder used by the user when accessing the OpenMRS registration module. This should be the profile that has the kiosk setup. Mine was called i2c33y1i.Registration.
3. create the tar file with the command: tar -cvf /home/<<username>> ./<<firefox profile folder>>. For me this was tar -cvf /home/user ./i2c33y1i.Registration
4. chmod 777 on the newly created tar file in the user's home directory
5. now sudo to root and create an init.d script, referred to in these instructions as <<firefox reset script name>>, to unpack the tar file and overwrite the firefox profile at startup. To do this create a text file with a name like 'firefox-reset' in /etc/init.d and chmod 755 on this file.
6. here are the file contents (fill this in with your local settings):
#! /bin/sh -e
tar -xvf /home/<<username>>/<<tarfile name>> --overwrite --absolute-names --preserve-permissions --directory /home/<<username>>/.mozilla/firefox
7. finally, to add the init.d script you've just created to the right run levels, type: update-rc.d <<firefox reset script name>> defaults
If the script doesn't work, or you want to stop running this script at startup, just type update-rc.d -f <<firefox reset script name>> remove
And, note, update-rc.d doesn't expect the path to your firefox reset script. Just type the name of the file. update-rc.d already knows to look in /etc/init.d.
Where is the Firefox profile folder?

Printer can't recognize the break between stickers OR the printer doesn't recognize the correct size of my stickers:
Here's the auto-sense printer startup routine:
1. Make sure the printer power is off and that the stickers and ribbon are loaded.
2. Press and hold the feed button then turn on the printer power.
3. Continue to hold the feed button until the status light LED flashes.
Release the feed button.
4. The printer will set the media sensor for the label backing being used.
After the printer is done making this adjustment, the roll will
automatically feed until a label is positioned at the print head.
5. The configuration settings will print. Upon completion, the printer will save the new settings in memory and
remain in diagnostic dump mode.
6. Press the feed button on more time. The printer will dispense another label with the
message "Out of DUMP" and be ready for normal operation.
How does the barcode printing work:
Barcode printing works as follows: when you click Print Barcode in the OpenMRS Touchscreen application, OpenMRS generates an .epl file that contains EPL2-language instructions that are to be interpreted by the printer. What you do is then configure firefox to automatically open the file with barcodeprint.sh. The barcodeprint.sh file is basically just a three line command file that routes the epl instructions to the printer device, which on Ubuntu should be /dev/usb/lp0 (see the code of barcodeprint.sh above). Then, the printer should execute the instructions. For more information on the EPL2 language, just do a google search for 'Zebra EPL2 Programmer's Manual'. This strategy is designed to do two things: first, you don't need a driver to install the printer. barcodeprint.sh basically fulfills this function. And second, we don't want to see a popup 'print' dialogue in Firefox -- when you click the 'Print Barcode' button, you just want the printer to spit out a barcode, no questions asked.
