2. Execute the Retrieve Printer Usage Statistics command.
3. Multiply the returned value by the factor given in Table 19 to get the actual
printer statistic.
Table 19. Retrievable Usage Data
Hex Value Usage Data Being Tracked Factor
80 FRU Card/Invalid usage numbers (set to X'0164' at the
factory, not set for FRU logic cards) N/A
81 Number of paper cuts 32
82 High byte of the number of characters printed on the CR
(thermal) station (see note 1) None
83 Low byte of the number of characters printed on the CR
(thermal) station (see note 1) None
84 Number of steps performed by the CR paper feed motor
(200 steps per inch of paper) 50 000
85 Number of times the customer receipt cover was opened None
86 Number of failed paper cuts – single-station printers only None
87 Number of characters printed at the DI (impact) station –
thermal/impact printers only (see note 1) 1 000
88 Number of steps performed by the DI paper feed motor –
thermal/impact printers only 50 000
89 Number of DI transport motor starts – thermal/impact
printers only 5 000
8A Number of home errors – thermal/impact printers only None
8B Number of times the DI cover was opened – thermal/impact
printers only None
8C Number of forms that were inserted into the DI station –
thermal/impact printers only 100
8D Number of MICR reads – Model TI4 only 15
8E Number of high-interference MICR reads – Model TI4 only 8
8F Number of failed MICR reads – Model TI4 only 8
90 Number of check flips performed – Model TI4 only 16
91 Number of check flip failures – Model TI4 only 8
Note 1: The number of printed characters is based on the number of dots that were printed,
assuming 64 dots per character.
Asynchronous (Real-Time) Commands
These commands are processed as soon as they are received. They do not go into
the printer buffer.
Note: These commands are not recognized when they occur in the middle of
another command. For example, sending this command after the second
byte of a 3-byte command, as in ESC J n.
