Claim:
1. A printing device comprising: a print mechanism that prints on a recording medium; a first receiver that receives data; a first receive buffer that stores data received by the first receiver; a second receiver that receives data; a second receive buffer that stores data received by the second receiver; a print controller that switches the target buffer to either the first receive buffer or the second receive buffer, and controls the print mechanism based on data stored in the buffer selected as the target buffer; a controller that (i) monitors if an immediate execution command was stored in the first receive buffer, and if an immediate execution command was stored, reads and runs the immediate execution command, and (ii) monitors if an immediate execution command was stored in the second receive buffer, and if an immediate execution command was stored, reads and runs the immediate execution command; wherein the controller does not delete the immediate execution command that was read and run from the first receive buffer, and deletes the immediate execution command that was read and run from the second receive buffer; and wherein the print controller reads the immediate execution command stored in the first receive buffer, and does not run the read immediate execution command.
