We moved an LP11 from our old 11/34 running V7 to a 750 running 4.2, and lp output is slower at times. It seems to pause for periods of several seconds. It also occasionally won't print the tail of it's output after a close until the next open. The system is never very loaded, and lpf >/dev/lp0 uses 15-20% cpu. The major significant changes I can see from the V7 driver is the code to disable interrupts at certain points, and the timeout stuff. Does anyone know the cause of this problem and a fix? Please reply by mail because I usually can't keep current in this group. Eric Gisin, U of Waterloo, (decvax|utzoo|allegra)!watmath!egisin.
