When you are setting your page size, if you set the page size to 36" (wide) in the driver x 190" (length), then your page size is 36x190 and the driver won't stop ejecting paper and won't cut the paper until the 190" length that you specified since you've identified that as the length of a "page".  You should set the length to only what you need for the job.  If you were using any wide format printer other than an HP printer, Qimage could automatically set the roll length for you and you'd never have to worry about the length... but honestly, HP drivers are very buggy and their drivers often don't conform to Windows standards: so you can't do things like specify length via software (it has to be done/saved in the driver so Qimage can't control roll length).  Anyway, just set your paper length to what you need as I suspect you don't need a 190" length.

The missing pieces in your print are also caused by an inability of the HP driver to accept large amounts of data while certain features in the driver are active.  Make sure there are no "automatic" settings enabled in the driver like automatic contrast or picture adjustments, etc. and take a look at the section of this article that talks about partial prints, all-black, or no prints.  It will instruct you how to set the spooler type to raw to reduce problems with printer drivers throwing away data due to memory issues:

Qimage sends more print data than your typical printing software due to its interpolation and sharpening.  If the printer is connected via ethernet, network queue size limits can come into play (it is better to connect via USB directly to the PC that is running Qimage).  As to the second job not printing, was the print size larger?  Did you load it from a saved job or setup: that could have loaded old driver settings and the "Effects" could be turned on in the driver for that job.

One other suggestion is to turn down your print resolution (on the Printers and Settings tab in QU).  If it's on Max (600) for example, turn it down to High (300) especially for larger posters.  There may also be other settings in the driver that have an effect on how much data they can handle; I'm not that familiar with the older DesignJet drivers.

I don't see anything inherently wrong in the settings.  The one thing I can't see are the Windows spooler settings so you'd have to check those manually in Windows Printers and Scanners: make sure "Enable Advanced Printing Features" is turned off and spool type is set to "Raw".  That's about all you can do.  You didn't say what PC and OS you are using and how much RAM is installed.  I see that the latest driver for the DJ 5500 is 2013: that's two years prior to when Windows 10 came out.  You might be experiencing some issues with the driver being so outdated.

hi mike, just looked at the trial version (which i am using and seen this highlighted, maybe this is my problem?)

hi, no i was only trying to print 3, i have since purchased the full version as i like the software but worry i have wasted my money as i still have partial print problems, i uninstalled the printer driver and re installed it, restarted my pc and tried to print 4 copies of the same image and still partial prints problem, also it only prints 1 off instead of the 4, not sure what is going on here, i have no problems printing files with the web access page and has never done a partial print in all the time i have had the printer, the latest driver i can find for my designjet 5500 42" is 2013 which is quite old, i am at a loss now totally frustrated also.
