One small fix, otherwise it’s very good

One small issue I had is some Fuji Xerox printers return the serial number of the toner cartridge in the output, however they include a semi colon “;”

This completely breaks nagiosgraph’s ability to graph them.

I added

MARKER_NAME=${MARKER_NAME//;/” “}

to check_one_consumable to replace the all semi colons with spaces to correct this
