Using hp laserjet p3005n, when I print one page it sends blank pg

all prints are blank or print 1 page after every print job?

try to remove the dimm. try to switch on without dimm. it not successfully than try to check the cables from the power board to the formatter. try to push them in thir place. If this is not successfull too than it is a formatter problem. try to change the formatter

The two most common problems that cause this are:

1. bad cabling. Check and make sure cables are properly seated and try a different cable if you have one.

2. wrong or corrupted print driver, try uninstalling and reinstalling the driver for the printer.

please download the driver form hp.com/support

First delete old documents.after tyr again print.

Yes it is.

Hello sir; I suggest , you may go to manu to reset the paper size in each tray.

Remove the network card and memory...see if it works OK with out them by printing a configuration page.

Sounds like a Procomm issue. Since I am not familiar with Procomm I can help you any further. But here is my analysis: All other application except for Procomm prints to tray 2. That is because all those applications use the setting as configured in your printer properties in Windows. What Procomm seems to be doing is trying to load a special paper from the manual feed tray, that is tray 1. You will have to check with in this Procomm application where you can change the printer properties so you can specify it to use tray 2 as the default. This is all within Procomm and has nothing to do with Windows nor your printer.
