print_fax, Canon printer goes off line

1. Printer going Off Line by itself

2. Minolta 1250w goes off line

When I turn the 1250w on to print the first document of a session, the
printer goes off line right away. I have to click it on to bring it back on
line. After that, it prints right away until I turn the PC off. Then, the
process repeats again. What is wrong?

Thank you.

3. Off line files go off line with solid wireless and VPN connection

4. Printer goes off line with restart

I have installed an HP 7310xi on my  wired network. It is plugged into the 
router. Both computers on the network print OK. Each time I restart, the 
printer goes offline. When I select "online", the printer will not show 
"ready" and does not print.

I must delete the printer and add it as a new printer at each start to get 
the "ready" icon and have the printer run. I have VISTA, and I have the 
latest driver updates from HP.

Can someone help?  Thanks

6. Printer goes off-line

I use a Samsung 1710 but it also happens to Panasonic so 
assume problem is with Microsoft software (XP).  I can 
print, but after leaving the system idle for several 
hours the printer automatically resets to off-line.  I 
can go into the printer software and reset to on-line 
again but it only gives, "error printing..."  Remedy: 
reboot with the printer power turned on.

Also other means fail.  Printer power on & off & on -- 
fails.  Printer reset to on-line and then print -- fails; 
etc.

Tried all types of settings and no luck, any help?

8. Printer goes off-line at shutdown

Everytime I shut down my computer, the printer goes off-line.  When I 
re-boot, I have to reinstall the printer, which then works fine until the 
next shutdown.

I read other posts and have verified that all the power management boxes on 
all USB ports in Device Manager are already unchecked.

Any other ideas re a fix?
