MyQ Desktop Client is able to monitor the number of printed pages on devices connected locally via a parallel port or a USB port. In such cases, the number of printed pages is extracted from the print spooler as it is being processed by the print driver. If the job is rejected due to breaking the policies or insufficient balance, the reason for rejection is reported to server.
If Credit or Quota (cost) is used, then a Price List needs to be assigned to the 'No Terminal' configuration profile.
LPM is supported on LPT, USB, TCP/IP and IPP ports. Monitoring of other ports may work, but it is not guaranteed.
LPM does not work properly with a printer that has the Keep printed document option enabled in the Advanced printer properties.
LPM does not work properly with a printer that has the "Enable advanced printing features" option enabled in the Advanced printer properties. This option is automatically switched off (if possible) for all monitored printers when LPM starts.
For further information, see Monitoring local printers in the MyQ Print Server guide.
