WP 34s flashing service Message #1 Posted by Michael Fehlhammer on 10 Dec 2012, 8:59 a.m. I would like to add IR printing capability to my 34s. Lately I bought a caculator with the real time hardware preinstalled (but not the IR diode), and it shows a version number of 3.1T 3303. Now I wonder if this ROM version already provides printing functionaliy, or if my calculator needs to be flashed after installation of the IR diode. I've learned that it's almost impossible to get flashing cables (or are there any good news?). So I need someone who could do the flashing (if necessary) for me, preferably a person or company from Germany or "nearby". Of course I am willing to pay a reasonable fee for the service. Can anyone help?

Yes, your WP 34S will need flashing. With respect to flashing cables 'old style' (see p. 147f), you may contact Gene Wright and ask if he still got one. Contacting him seems to be nontrivial for whatever reason(s), however. If you have the IR diode and resistor installed, I can do the flashing for you if you want me to - provided you pay the postage. Just drop me an email via the Museum Mail. d:-)

The printing commands are present in all images but they do nothing useful except from the IR image. This was done to maintain binary code compatibility between the different 34S firmware revisions. - Pauli
