root / pykota / trunk / cgi-bin / pykotme.cgi @ 2381

Revision 2381, 7.1 kB (checked in by jerome, 19 years ago)

Doesn't display the list of printers when the CGI script doesn't require an
authentication, because the size of the job doesn't depend on the printer
being used. When there's authentication, the exact cost of a print job
depends on the printer(s) chosen and the user's overcharging factor.
