p.s. My source for the ESC/P2 are old retroware/retro-computing software and the data will be coming out of 8-bit system emulators. I am hoping programs like xtrs (linux) and TRS32 (Windows XP) could use this driver.

Most long-term users of personal computers got their start in the 1970s and 1980s, playing with — and sometimes even getting work done — on machines like the original Apple II, the Tandy TRS-80 and the venerable Commodore 64 and 128. While these are nostalgic names for a lot of users, there are a lot of users who still actually use the things. The March issue of Wired looks at retroware, the growing use of older computers, in an article by Mark Frauenfelder titled "Never Say Die."

For all of Microsoft's effort to make Windows 95 a high-performance game platform, you may have to wait a while before you can play any titles designed for it. Some game developers — Mindscape, for one — have aggressive Win 95 plans, but others, like LucasArts, haven't announced any games designed for the long-delayed operating system. Microsoft itself has shown only two games for Win 95: Fury3, a Descent-like flight sim, and Return of Arcade, another retroware disk.
