We're using SCO Xenix 2.2 with parallel line printers . There are two things we don't understand: 1. The problem which occured is that the printer would not work as fast as possible . The printer is connected to the parallel port of the Hercules-Card. The spooler seems to work correctly. First we thought, that the terminal processes accessing the graphics card would slow down the supplement of the printer. But connecting the printer to a serial/parallel interface card had the same effect; also 'cat file > /dev/lp[0,1]' . The manual does not give us any hints. What's wrong ?? 2. What is the standard number of NBUF and SABUF ? Are there optimal values differing from the default values generated by the kernel during startup ? AND: what are SABUFs ?? Please reply directly to : (If anyone is also interested in the answers, let us know. We'll forward the useful ones .) ________________________________________ | Usenet: wichert@quando.uucp | | UUCP : ..!unido!quando!wichert| ________________________________________ Thanks, _ __ _ ' ) ) _/_ ' ) / / _/_ /--' _ / _ __ / / / o _. /_ _ __ / /
