A printer (103) belongs to a service set (107) and communicates via an access point (101) in the infrastructure mode. The printer (103) searches for a beacon periodically. If a beacon is received from a terminal such as a digital camera (104), the printer registers the terminal address, service-set identifier and communication mode, which are contained in the beacon, in a function table. The printer sends each terminal, which has been registered in the function table, a frame that is for searching for a terminal that has a required function. If the response to the frame is positive, then the printer registers the fact that the search succeeded in the function table. A similar function search is conducted also by a digital camera (104) for which a print command has been issued, and the digital camera creates a function table. If there is a terminal (a printer) having the required function, the digital camera (104) transmits print data to this terminal.

Compressed stride tables in a multi-bit Trie structure perform lookups. An input lookup key is divided into strides including a current stride of S bits. A valid entry in a current stride table is located by compressing the S bits, forming a compressed index of D bits into the current stride table. A compression function logically combines the S bits to generate the D compressed index bits. An entry in a prior-level table points to the current stride table and has an opcode field indicating which compression function and mask to use. Compression functions can include counts of leading-repeated bits, and very complex functions such as hashes, CRC, encryption. A function table stores results of the complex functions that are addressed by the S bits of the current stride. The opcode field in the stride entry selects from among several tables, each storing results for a different function.

A numerical controller capable of operating an auxiliary function at a target time or spindle position in performing operation based on table format data. An auxiliary function table is stored with auxiliary function commands M to be outputted corresponding to commanded reference times Lc and their corresponding operation delay times D.
