7.5.5.5 Other questionnaires
Other probable questionnaires are described below.
7.5.5.5.1 Time required for creation of Certificate
Time required for creation of Certificate Time is shown for each key size.
(It can change in the range of -30 to +30%.)
Table 7-5 Certificate creation time (For RSA) Unit is in second.

7.5.5.5.2 Communication time when the encryption function is enabled
Result of comparison between the communication time using encryption and the normal
communication is shown below.
Web top page browsing time is shown.
Web top page is the web screen for setting printer, and is displayed first.

Also, communication time for IPP print is shown below.
PCL NULL Data (31,464,978 bytes) is used as the print job.
(NULL Data is the data that receives process which enables measurement of maximum
communication speed of network communication by minimizing the PCL processing.)

7.5.5.5.3 Can the encrypted printing be performed by any printer other
than IPP?
Answer: Any printer other than IPP cannot encrypt printing.
Only the IPP printing can encrypt printing.
7.5.5.5.4 What will happen if SSL/TLS is turned OFF after Certificate has
been created (or installed)?
Answer: Certificate will be kept saved as it is.
If SSL/TLS is turned ON again, the Certificate becomes usable.
7.5.5.5.5 Want to change the port number
Answer: The port number during the SSL/TLS communication is fixed to 443.
It cannot be changed.
