Re: lpt0 always busy
It seriously looks like the printer, cable or port are broken, or the printer is very very special.. What sort of printer is it? its a canon lbp 460 - ugly gdi printer :) You could try printing to /dev/lpt0.ctl since that will ignore BUSY for the open. one can print using lpt0.ctl? - thx 4 the hint - i'll check this ... thx regards, stan ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: lpt0 always busy
hi, i am now trying for weeks to get my lpt0 working without any success :( i always get device busy (running lptcontrol, lptest, open(/dev/lpt0)). i found a lot of questions about this via google and some hints too (e.g. excluding device ppi from kernel) but all this didnt help :( i should mention that my printer connected to lpt0 is a funny gdi printer which only works under win98. so my idea was to use qemu to run a emulated win98 to get my printer working - but therefore qemu needs to be able to open /dev/lpt0 ... finally i wrote a simple c prog which just calls open(/dev/lpt0) but it also always fails with device busy :( what are the requirements to successfully open lpt0 port (apart from having connected a printer to it) ? does fbsd expects a response from the printer (e.g. ready status)? maybe my printer is not able to do this ... if so: what are possible workarounds? could i convice the kernel that lpt0 is ready? thx regards, stan ps: i am running fbsd 5.4 Usually, if you get device busy, it means that the printer is simply not on or connected properly. Check your parallel cable. unfort. my printer is connected properly and it is on while simply trying to open it with open(/dev/lpt0) - lptest /dev/lpt0 fails too ... so it seems that fbsd expects some kind of status reply from the printer - correct? if so: how could i by-pass this?

Re: [EMAIL PROTECTED]: lpt0 always busy
Can you get hold of a simpler printer, one that uses the HP500 driver for example, and test your port? I tend to think it's a driver issue, at least until you can rule it out. I've had this problem on a NetBSD system, for example, which got solved by switching to just such a simpler printer and driver.
