hp 960C connected to w2k sytem working fine; then suddenly get error message and can no longer print. Error message states that there is 'a system failure, re-install printer drivers'. Downloaded updated drivers from hp website, followed instructions...same outcome. Performed self-test on printer, diagnostic test on printer and cable test (replaced with working IEEE cable from different machine). Tried printing from dos prompt i.e. dir>lpt1 and get no response. Is the printer, the cable or the parallel port that's frazzled? Parallel port using ECP with no DMA call.
