Abstract:
1. A printing device connected to a client, the printing device comprising: a reception unit which receives plural types of logic packets from the client; a hardware packet processing unit which processes logic packets by hardware; a software packet processing unit which is implemented on a microprocessor and processes logic packets by software; and a sorting unit which is not implemented on the microprocessor and sorts the plural types of logic packets into one or more types of logic packets to be processed by the hardware packet processing unit and one or more types of logic packets to be processed by the software packet processing unit, wherein the sorting unit sorts a reply-requiring logic packet, including contents for replying to the client, as a type of logic packet to be processed by the hardware packet processing unit when sorting the plural types of logic packets; and wherein: the sorting unit sorts a credit request packet for transmitting print data as the type of logic packet to be processed by the hardware packet processing unit when a high quality print mode is set and sorts the credit request packet for transmitting the print data as the type of logic packet to be processed by the software packet processing unit when a low quality print mode is set.
