[Discuss] Printer issues

[Murray Strome]

I am running Kubuntu on two different computers, using CUPS. I will call 
them A and B. I have never had any difficulties until recently.

On A, I have an HP DeskJet 670C.  Recently, it just quit working. In 
LINUX, it is not even detected anymore. Under System Settings > 
Printers, if I try to add a local printer, that choice is grayed out.

I loaded the old Windows 98 to see if it would work with that.  I get an 
error saying there is no communication with it. I have checked the 
cables and everything and they all seem to be OK.

On B, I have an Okidata OL600e, which is my "work horse" for printing.  
If I am printing from B, I seem to have to restart the print server very 
frequently.  To print from A, it seems I have to go through a lot of 
contortions to get it to print. When I try to print something, it says 
it is doing it. Before doing the print, it says the Okidata is ready and 
accepting print jobs. However, nothing actually prints. When I look at 
the settings, there are no jobs pending.   Sometimes, after I reboot 
both computers, things will work OK for a little while (usually less 
than an hour). 

Any suggestions as to why the DeskJet is no longer detected, or as to 
why the Print Server has to be restarted almost every time I want to 
print something?

Thanks for any help.
