Patent attributes
A printer receives print information from a host apparatus. An image memory stores image data produced from the print information. A total quantity of output detector determines a total quantity of output that should be printed. A reference quantity storing section stores a reference quantity. A comparing section compares the reference quantity with the total quantity of output to determine whether the total quantity of output is larger than the reference quantity. If the total quantity of output is larger than the reference quantity, a controller reads a fraction of the image data from the image memory and sends a first command to a printing section. The first command causes the printing section to perform test printing where the printing section prints the fraction of the image data and then enters a standby state.
