I built up a desktop machine for a friend during the time 8.04 was current. It was duly upgraded to 10.04 and it has been trouble free right up until a week ago when the PSU "gave in", and took out the rest of the works (as I found out as I tried to persuade it to work again).
The only cure was to build a new machine. Having now built it, and loaded it with 12.04, and its updates (including the "classic" option), I am left with the following most peculiar problem......
It recognises the printer and will happily shunt a document down to the printer but it will not print it. The printer will accept the "print test page" command but will only print a page with a column of mainly capital "M"s down the left hand edge of the page.
Peculiarly the printer will print a perfect test page quite happily on my standby desktop machine which is on 12.04.
Can anyone, please, throw some light on this strange business?
