Since I cannot attach a printer, will the AVIEW and PRBUF functions be active in the program? It is my understanding a printer needs to be attached when entering the program manually. Am I wasting my time trying to enter the program on my Android?

In general, you cannot enter any commands of a peripherical device unless it is not attached to the calculator. So you can't enter a PRBUF without the printer, or a RTDAX without the card reader.

I don't know how this affects GO41CX, but for real 41's, if you have the HP-IL module plugged in (which has the printer and other I/O functions), you can enter the printer functions (like PRBUF) without a printer attached. The HP-IL module can support lots of printers at once as well, and if you really had more than one, you would select which printer you want. I've never had more than one actual printer attached at once, but I've had a printer plus other things I could SELECT and output to as if they were printers.
