Setting it up

The plotter is an HP DesignJet 300. It is connected to the network using an HP JetDirect EX interface. The printserver's IP address is Please don't change the printserver's IP address or configuration, it is not at fault.

With a Mac Not sure about Macs. Based upon what's in the Use the Printer HOWTO, this seems pretty straightforward. Just know that "port 9100" is the protocol to use, and if it gives you a choice between PS and HPGL, use HPGL.

With Windows On a Windows box, you need to ignore the temptation to click "add a network printer", and instead, "add a local printer", then "create a new port", then port type "standard tcp/ip port", then enter, and everything else should be sensible.

Since this is an older plotter, HP is no longer writing the drivers for Vista and later versions of Windows. However, there is a set of drivers available for Vista and Windows 7 here: Use them at your own risk!

How Much Does it Cost? The cheapest HP plotter paper is about $0.15 a foot. Throw some money in one of the jars when you're done. :)

Loading Roll Paper First, do you need to? If the plotter is off, and it looks like the paper is loaded, turn it on. After a few minutes of self-testing and moving the paper around, if the lights settle on Plain, Normal, Ready, and Roll you're good. If not:

When the Load Paper light is on solid, insert the end of the paper until you feel a stop and the plotter starts to pull it in. When it stops, the Load Paper light will flash. Open the cover and you'll see it lift the guide bar. Flip the green handle on the right down to release the rollers. Align the edges of the paper so it feeds straight in. Slide the paper so that the right edge is over the punched slots on the metal edge where the paper feeds in. Flip the green lever back up to lock the paper in place. Close the lid. The plotter will pull the paper back in but the edge will still be exposed. Wait for the Ready light to stop blinking. You're done!

When You're Done

Before you walk away, make sure that the printhead is "parked" on the left side. If an error occurs during plotting, it will sometimes stay out over the paper. Leaving it this way will allow the printhead to dry out and clog. To check, just lift the hood from the center and see if the printhead is over in the well on the left side. If not, power-cycle the plotter and it will both clear the error and park the printhead.
