After realizing that I couldn't print more than 15-20 pages at a time using the Shareport utility, I called D-Link's technical support and after 50 minutes, was told by their support staff that I can't use Shareport for print jobs larger than this (I wish they could have told me this at some point earlier in the conversation).
I find this hard to believe, although at the same time, the tech support person told me that because I was able to print small jobs, there was nothing wrong with Shareport itself (plausible, I suppose).
Does this match the experience of others using Shareport? I have it on a D-Link DIR-655 wireless router, with two computers (laptop and desktop), both running XP SP3, connected to my HP Laserjet 1018 via a USB cable (to the router). I get the same poor results regardless of the computer I'm using.
Is there anything I can do? The tech support rep didn't give me any troubleshooting or settings to check after I told her that my firmware and Shareport were both upgraded.
