I am unable to print the block diagram on a HP1055CM DesignJet.

The print manager shows it went to the printer but all I get is a blank page on the printer. Is it maybe a font problem?

There are many things that can go wrong when you print.

The first thing to try is if LV is generating the proper draw instructions for the printer. Try to print to an HTML file (this is one of the options toward the end of the File >> Print dialog), and see what the file looks like.

Typically, print error occur because of the printer's driver. Check to see if the driver for the printer is the most recent (by looking on the printer manufactorer's website).

Use this link to an article that details printing problems, and their solutions: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/0a124f6b3a94a82f862569680071cd48?OpenDocument.

It will walk you through what to do, and has a VI attached that will extract your printer information
if you are still having an issues after trying the things detailed in the knowledgebase.

Hi DGosnell,

There have been reported issues with some HP Plotters/Printers and LabVIEW 7.0. Some of these problems have been addressed and resolved in LabVIEW 7.1. If possible, see if you can get a copy of 7.1, make a backup copy of your vi, and then try it on LabVIEW 7.1. Also, it would be a good idea to make sure your HP printer drivers are up-to-date.
