The Assistant Collector also appears to have confused the DZM-180 with the DZM-180 RO. Their machine is not RO and it has no application in telecommunication. He referred to their catalogue for the mosaic-type character printer. He drew special attention to page 17 and the paragraph runs thus: The CI signal should be maintained by the co-operating external equipment until the printer sends the PEC signal (receipt confirmation) which means that the character code has been entered into the register on the Logic Board. The external equipment may send a new character with .....

These options were not available in the imported printer under consideration. The Scientific Officer also told the Assistant Collector that the DZM-180 printer did not fall into the category of machines for transcribing data onto data media in coded form in terms of para 3, 3(i) and 3(ii) of his (Assistant Collector s) letter. 3. The learned counsel referred to the Brussels Trade Nomenclature definitions relevant to computer sub-systems and said that a reading of these definitions would satisfy anyone that the machine they have imported is connectable to the Central processing unit, is specifically designed as part of such a .....

A serial unit prints one character at a time in the manner of a conventional typewriter, whereas a line printer prints a line, usually consisting of 80 to 132 characters, at the same time. An impact printer uses direct mechanical force to produce character images on the paper, whereas non-impact printers utilise various electrical or mechanical processes to form the characters. 8. The learned SDR read from the importer s literature and said that this paper; suggests that DZM-180 can act not only as a telecommunication printing device but also as a long distance typesetting machine. 9.

Application examples : - main or auxiliary printer for mini-computer systems - computer output device - device co-operating with a monitor - printing device for telecommunication applications etc. 12. The possibility of coupling it to a keyboard indicates that it does not need a keyboard for its operation. Evidently, therefore, a hook-up in a telecommunication system when the printer receives input signals from a remote station will activate the printer to print its output. This, in fact, is a well known characteristic of such printers ..... X X X X Extracts X X X X X X X X Extracts X X X X
