based on an obvious-to-try argument (e.g., Br28-29) because there
is a certainty that the combination will work.
The print engine start time in Zimmerman, which is the time
of "performing a print environment recognition operation at a
print recognition time" as modified by Saruwatari, is the time
when the I/O buffer reaches the buffer threshold. This "print
recognition time" is "determined in accordance with said
transmission time." That is, the system calculates the
transmission time, which is how long it takes to send the data
for a certain transmission speed (e.g., 8.0 million pixels/page
(1.0 million bytes/page) and a data transfer rate of 50
Kbytes/sec would take 20 seconds), and determines an appropriate
buffer threshold "in accordance with" this time (e.g., 400,000
bytes to store 40% of the page) (see col. 5, lines 26-39, and
note 50 Kbyte data rate at line 39). The buffer threshold is
"determined in accordance with said transmission time" because
the size of the buffer threshold is dependent on the transmission
time; longer transmission times (due to slower transmission data
rates) require larger buffer thresholds and vice versa. Thus, we
conclude that the combination of Zimmerman and Saruwatari would
have suggested "performing a print environment recognition
operation at a print recognition time, said print recognition
time being determined in accordance with said transmission time."
