I'm confident HP will fix it. As soon as I can profile 11x17 sheets that is.
The only thing that can be said with 100 percent accuracy is that two of us received diametrically opposed responses from HP. HP tech support for the APS in Idaho talked to the design engineers for APS and told me that there are no confirmed plans to fix the 24" limitation for the largest target. Panascape has been told the opposite by the team in Spain. Since HP doesn't post on this forum -- and HP doesn't even post on their own forums (which are completely useless for that reason) -- no one knows for certain what HP is doing.
So don't engage in wishful thinking and simply hope that dreams come true. You're hoping that HP will fix it because like the rest of us, you bought a $4000 printer, and premised that on HP's advertised claims for the APS. Now you discover after placing the order that the APS is junk that doesn't work except with 24" paper, and apparently doesn't work at all with an official HP-branded paper.
Join the crowd. No one even knew about this problem until I discovered it and posted it in the first thread on this topic that you can find here:
Bottom line -- Don't buy based on the promise of a beta version. Don't even buy based upon delivery of an actual beta version. None of that helps you.
Don't buy until you know that HP has officially released a new version that fixes these problems.
Otherwise, you are just a sucker being separated from his money. Unlike the rest of us -- who didn't know about this problem -- you've been warned.
If you really want HP to feel the pressure to fix the APS, the best way is through the marketplace -- by not buying the software. If no one is buying the APS, then HP will feel the pressure to fix the APS asap.
Nothing gets the attention of a company faster than a halt to sales.
