Top margin
The set value is received from the digital copier, and data are made
according to the set value.
Left margin
Since the paper size sensor is not set, the digital copier cannot recog-
nize the size and direction of paper which is actually inserted.
Therefore, the left margin is set according to the paper size specified in
the print data sent from the computer, and print process is performed.
If the computer does not specify the paper size, or in the case of the
custom size, the left margin is set according to the default paper size.
