IBM 6400 Matrix Printer is printing twice over a previous line it seem on to happen once or twice per page of text there seems to be no issue with the tractor feed no drag on the paper source and the test prints seen alright thanks in advance

Driver, the printer can't even hold one page in memory let alone many pages.

What driver are you using for the printer?

Also, when you go to print the document, you will see a printer listed on the top of the print menu screen.

Next to that, there will be a down arrow. Click on the drop down arrow and select the IBM InfoPrint printer you want.

Load the drivers from IBM's web site. But.. depending what Windows ver. you are on go to install new hardware. Windows will find the drivers itself.

Try running couple of these test, to see if it might be another issue.
It should be printing these test at 1500 Line Per Minute... ?
1500LPM is at 10CPI if you have (Font size: 6, 8, 12, 14) it will make a difference.
Change your driver to Generic/Text, rerun your report... any difference?

it should have kept the same address

Sounds like the configured paper sized does not match the actual paper page height. So that when it does Top Of Form paper movement the paper stops slightly too low. Doing several form feeds should confirm this. If this is it then reconfigure the paper size to match the paper. Also measure to paper to see if it matches what you want it to be.

Dec 18, 2007 old problem... If you have same problem currently, post it and will get you fixed. March 14, 2009.

Did you check the lines per page setting on the printer? For normal 11" length forms, the setting should be 66lpp.
