Hi Michael, Raymond, guys;
Raymond is correct in all aspects; I just want to add some data, O.K?
The HP82240B offers two character sets, being ECMA94 and ROMAN8, while the HP82240A has the ROMAN8 set, only. ROMAN8 is closer to previous HP82143A (HP41 standard peripheral printer) and HP82162 (HPIL portable printer), and I am not sure if it is, in fact, the same.
The "early" HP48 series (S/SX/G/G+/GX) allow the use of both printers: A or B. If you want to use the A-series, there is the need to remap the IR output, and you need to execute OLDPRT. If you want to use the B-series after that, you need to purge PRTPAR so the remapping feature is reset.
I guess that if the HP49G+ manual states that the IR output is defined for an HP82240B and if there is no OLDPRT command available, then you may use the HP82240A but some characters coded 128d to 255d will not print correctly (in fact, the standard ASCII character set, from 32d to 127d, doesn't need remapping: A to Z, a to z, 0 to 9 and standard punctuation). As both printers use the same "IR" protocol, I see no trouble using an HP82240A with an HP49G+. Maybe you should test first to see if there is nothing wrong.
The only additional characteristic is that there is an extra blank "pixel" row between strings when printing text only. You may have noticed that there is almost no clearence between text lines in an HP82240A listing. This is because of its graphics capabilities, so there is only one blank pixel row between lines. In the HP82240B, all characters are one row "shorter", but it eases reading.
I think that's all. Hope this helps.
And please, if I missed some code or equipment ID, forgive me: I just have no manuals in hand right now, this is all written "by heart". (I edited the message to add this)
Cheers.
BTW, the reasoning is: is there any chance that the HP82240B is getting back in production? A new design perhaps? Or it's alreadyhappening and I am not aware of this? Anyone taht knows something about this?
