The Printronix P7000 series of line matrix printers are still manufactured as of 2013. Line printers are the fastest of all impact printers and are used for bulk printing in large computer centres. A line printer can print at 1100 lines per minute or faster, frequently printing pages more rapidly than many current laser printers.
Daisy wheel printers were added to the line with a purchase of the business from Plessey in 1978. A joint project with Exxon yielded a series of solid ink printers. The Exxon printer division was Danbury Systems Division where 6 members were hired by Howtek, Inc, the company producing the Pixelmaster Solid ink Color printer. [3]

HP 9830A, introduced in 1972, was the top of the 9800 line, with the addition of a BASIC interpreter in read-only memory (ROM). HP itself referred to it as a "calculator". [4] All 98x0 and 9821 systems used the same I/O interfaces. [5] A 400 line per minute 80-column thermal line printer was designed to fit on top of the 9820 and 9830. [6]
The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) is a network printing protocol for submitting print jobs to a remote printer. The original implementation of LPD was in the Berkeley printing system in the BSD UNIX operating system; the LPRng project also supports that protocol.
