I've got a block diagram 50 50 and electronic description.

Unfortunately, the strobe (PI) … … 76 77 we cannot simply use commands like "cat $file > /dev/lp0" at Linux 77 78 or "copy FILE.TXT LPT0:" in DOS/WINNT, but we need an own driver. 78 79 79 80 In this subproject, we have implemented the diagram above as 80 81 program logic. To keep it more simple, we didn't develop kernel 81 82 driver, but userspace / user mode drivers, using ppdev at linux and 82 83 the third party library "WinIo" at Windows NT. 83 84 84 85 85 86 Sven Köppel, 86 87 documentated at 02.
