Error Message 40: HP P4014, P4015 & P4515 Printers. Error 40 looks like there is some communication problem hitting a network card. Most modern communication protocols allow some level of error (older communcations like RS232 and parallel-ports didn't always do so). This may be a residual error from those days, or might be invoked when a network link descends to chaos. 40 EIO X BAD TRANSMISSION Any communication link can fail.

Most but not all communication programs attempt to detect and correct errors, so a TCP telnet link (for instance) can recover several minutes later (or hours) after being unplugged. Not all protocols are so tolerant. A printer really needs to either finish a task or move on so if print information ceases or contains uncorrectable garbage the printer will say so.
40 EIO X BAD TRANSMISSION 'To Continue Press OK'. EIO cards are the slide-in communication modules in the back of printers. There can be as many as three EIO positions in big machines like the LaserJet 9500, allowing them a hard disk and two network cards.
