4.7 Restrictions by the Printer
4.7.1 Printing time
8 pages of A4-size paper per minute
As illustrated above, it takes about 7.5 seconds to print on a page of A4-size paper by the
printer used in FX-051. While the printing time is fixed, the communication time varies
considerably depending on the complexity of the document image. To match the printing time
to the communication time, FX-051 starts printing after receiving the image data for a page.
FX-051 prevents memory overflow by controlling the communication time by the following
method.
