printing problems with xp and adobe

I have a folder on a nt 4.0 server that has .pdf files at our main site. At a satellite site connected by a t1 I have an xp pro computer on the network. We are pulling files from that folder on the network drive. I have adobe 5.0 on the xp box. When I am on the xp machine and goto the network folder, then select all, then print, I am trying to print all files in one shot to a lj5si but not all the pdf files print. The folder contains around 45 pdf documents and not all of them print out unless I print them one by one. Does anyone have any suggestions….
