Some success, but...
Lurking on this thread, I thought to meself: a bi-directional server - good, esp. as I can then link 'er indoors to the scanner and me to the photo printer rather than the rather convoluted 'shared printer route I've used so far. (I have a Netgear PS121 connected to the laser, which is rock solid, and useable by us both, but can only handle one USB connection and is unidirectional.)
So, Like Keef, I ordered a TP Link. Arrived this morning, and installed with only minor looking-for-software pauses. Good. On both computers. Good, er, not so good.
Turns out that if I print a page from my m/c, I have to 'release' that link before 'er m/c can use the printer. Since we typically have sessions when we're both working like mad, printing a few random pages each here and there, this is a nuisance.
I'm wondering if I can play with some 'time out' function in the server to 'release' the link, without then having to log back on again to print.
No more time to play now, but if anyone has useful comments to hurry things up, then fine; otherwise I'll report back / wait to see how Keef gets on with the beestie.
