Self Identifying Print Belt for Line Printers

Print belt 10 (Fig. 1) contains conventionally formed character shapes and timing marks 12. In addition, another area of belt 10 carries coded indicia 13 identifying which particular font and character set 11 are on the belt. Indicia 13 may represent any conventional code.

In Fig. 2, belt 10 is mounted in a printer 20, trained around pulleys 21 such that print hammers 22 can strike paper 23 against the characters on the belt. A read head 24 conventionally reads timing marks 12 (Fig. 1) to monitor the current belt position. Here, head 24 also reads coded indicia 13, so that signals representing the identity of the particular belt mounted in printer 20 can be sent to a data-processing system.
