To print a form, you must load the paper in the printer and use a command to mount the form, which notifies the LP print service that print requests submitted to the printer are to be printed using the form definition. If you use one printer for different types of printing, including forms, you should:
Disable the printer before you load the paper and mount the form.
Re-enable the printer when the form is ready. Otherwise, the LP print service will continue to print files that do not need the form on the printer.
When you mount a form, make sure it is aligned properly. If an alignment pattern has been defined for the form, you can request that the pattern print repeatedly after you have mounted the form until you have adjusted the printer so the alignment is correct.
When you want to change or discontinue using a form on a printer, you must notify the LP print service by unmounting the form.
