I've written about specifying drivers for redirected printers in the past, but it's not something I've had to do for a few months.
Last week we had to get a 1500 series HP PSC working on a home workers terminal server session, and it turns out that the “proper” driver isn't correct and doesn't install. Luckily it seems that a lot of the HP PSC's use the same internals as the HP Deskjet series. As most of the Deskjet series work with the Deskjet 550C driver we tried the 550C for the HP PSC 1500, and it works like a dream.
Just thought the world might be interesting in knowing.
