How many pages have I printed?

It's not possible (yet) to find that out as a simple number. But you can look up:

1. a list of the jobs and the number of pages printed during previous billing periods
2. a list of all of your print jobs this month and last month.

For the record of jobs for previous billing periods, use this web page or run this command on ms or your linux workstation:
previous-print-jobs

You can see a list of your print jobs for the current and previous months with these commands on ms or your linux workstation:
recent-print-jobs --thismonth
recent-print-jobs --lastmonth

NB: if you run the command recent-print-job on ms, you will see all of your jobs for the month, but all jobs submitted from a linux workstation will show as only 1 page; if you run the command on a linux workstation, you will see the correct page counts, but only for those jobs submitted from that workstation (this is not the case with previous-print-jobs, which uses conflated logs). Yes, a pain, but something we're working on.

Why is Acrobat Reader (acroread) not working when I printer using kprinter?

Use 'kprinter -c' instead of 'kprinter.' You probably don't really want to know why, do you? Note that Acrobat 8 doesn't require kprinter; it brings up a proper printer-control dialogue box on its own.
