A VTAM application can print directly to an LU1 or LU3 printer. Other applications would have to use an intermediate SYSOUT, in which case you would need a Functional SubSystem (FSS) that supports your printer. Does the 4224 support IPDS?

I am aware the 4224 came in a number of configurations. When I got it, it had a (broken) twinax interface in it, intended for an AS/400. I found a 3270 coax interface that I put in, which doesn't yield any error messages on the printer. As mentioned, the printer is recognized by the 3174 without issues, see [1], port address 03. As far as I know the 4224 came also in IEEE-1284 and ethernet variants. Not sure about EIA-232. > You might have one that is not usable with OS/390 without special > hardware (there is an adapter card on the 3174 for it, for example. Are you referring to the Asynchronous Emulation Adapter for the 3174? I am aware it exists, but I don't have one. It adds EIA-232 ports to the 3174. Probably not applicable in my case anyways, as my 4224 has a 3270 coax port. > You'd have to determine exactly what model of 4224 you have, and > then configure the 3174 appropriately. I don't think there is much to do on the 3174 really, at least I haven't found any configuration screens that seem relevant. > I don't think it is a VTAM logmode issue (yet).

The 4224 is what I have. > The 4224 claim to fame was that > it could handle a high volume of dot matrix multi-part form printing at > high speed. True. > Unlikely to be useful these days :) This is an archaeological activity, not a production deployment :-) At the moment I do not have enough knowledge about how printing works under MVS-type operating systems. Assuming a printer connects to VTAM successfully, then what? How do I 'send' something to a printer? This is probably described in an IBM document somewhere, but I haven't found anything helpful so far.
