Problems Getting Printer to Work After Upgrade to Solaris 2.5 on a Sparc 20

by esch.. » Wed, 27 Dec 1995 04:00:00

i am having problems getting my printer (an hp series iv laserjet) to work after
upgrading my sparc 20 to solaris 2.5. i keep getting an error that says the printer
port could not be opened. everything looks like it is set up correctly and that the
proper device is being used for the serial port (the job gets spooled, but then
eventually times out because the printer port could not be opened). i have tested
the printer on another sun workstation running solaris 2.5 and it worked.

i would appreciate any suggestions on what i might do to determine how to correct
this problem! thanks.

1. Solaris 2.5: IPC gets faster, Sparc 20 gets slower?

Hi,

I have installed Solaris 2.5 on two machines: an IPC and a Sparc 20
with 2 50MHz processors. The IPC has 36 MB of memory and the Sparc 20
32 MB. The latter is being upgraded to 64 MB.

Currently, though, I notice a pretty dramatic improvement in speed
over SunOS 4.x on the IPC. The Sparc 20, however, seems to have
thrown an anchor into the seabed. There seems to be a lot of disk
swapping even though there is only one user.

Any ideas where to start? When there is more than one user (there is
a xterminal hooked up to it) and a user running X on console, I can
sort of understand the swapping, but it did not do this under 4.x.

Another quick question. A while ago I asked about how swapping work
under 4.x. I was told that 4.x swapping allocated space everytime you
started a program, regardless of whether it was needed. I was also
told that 5.x didn't do this, only when it was actually needed.
Anybody care to clarify this for me?

Thanks,

Kevin
