Guest JohnT Posted October 26, 2008 Posted October 26, 2008 A few days ago I installed the following updates on my HP D530 running Windows XP Home SP2: KB956803, KB956391, KB957095, KB956390-IE7, KB954211, KB956841, KB958644. Today I found that the HP 932C parallel printer would not work, as it had before the update. I verified that the printer worked using my old 98 machine, and verified that the port worked using another device. Uninstalling and reinstalling the driver had no effect. I found that LPT1 was set to Never Use Interrupts. I thought this an odd setting for background printing; I suppose it could use DMA, but that seems like overkill. At any rate, I set it to Use Any Interrupt and printing started working again. Has anyone else seen effects on LPT1 from any of the recent updates?
