The message is encountered when printing on older HP LaserJet printers such as the LaserJet II, III, and 4 series. It means that the printer is trying to print a document that needs "Letter size" (8½ × 11 in.) paper when no such paper is available. [3] Early LaserJet models used a two-character display for all status messages.
Printer Job Language (PJL) is a method developed by Hewlett-Packard for switching printer languages at the job level, and for status readback between the printer and the host computer. PJL adds job level controls, such as printer language switching, job separation, environment, status readback, device attendance and file system commands.

The LaserWriter used the same Canon CX printing engine as the HP LaserJet, and as a consequence early LaserWriters and LaserJets shared the same toner cartridges and paper trays. [14] PostScript is a complete programming language that has to be run in a suitable interpreter and then sent to a software rasterizer program, all inside the printer.
