MSDOS doesn't use an interrupt driven printer driver. : It seems that my printer doesn't know that is supposed to return an : interrupt. (?) This is doubtful. : 1. Will changing the SoundBlaster interrupt setting fix this problem? Yes, or change the printer interrupt, whatever is easier. After you change the settings on the card(s), you can boot with '/kernel -c' and set the irq's properly. : 2. Should I reduce the timeout value for the interrupt on lpt0? If so, : how? No. : 3. Is there any way to do away with this interrupt requirement on lpt0? Yes, you can use 'lptcontrol -p' to change to a polling, rather than interrupt driven, printer driver. See the man page. Use of polling type drivers is generally frowned upon in Unix circles, however. -- Tom Rush tom@tarush.chattanooga.net
