When you have defined a form for the LP print service, you can check the form with either of two commands. Which command you choose depends on the type of information you want to check.
To show the attributes of the form, use the lpforms command. You can also redirect the output of the command into a file to save it for future reference.
To display the current status of the form, use the lpstat command. To protect potentially sensitive content, the alignment pattern is not shown.
If you are not sure about the name of an existing form, you can view the form names by listing the contents of the /etc/lp/forms directory.
