Problem

When I try to print from Microstation to my HP Designjet 1050C the printable area is always decreased by 1.05 inches in the paper flow direction. How can I reduced that number? 

Solution

The following settings are what you would need if you are using Roll media instead of cut sheets.
Go to "Pnters and Faxes"on your Print Server  Right click on your printer, select Properties.
Click on "Printing Preferences...". Change "Paper source" to "Roll" and set the "Roll size:" accordingly.
Go back to "Properties" on the device and select the "Advanced" tab.
Click on "Printing Defaults...". Change "Paper source" to "Roll" and set the "Roll size:" accordingly.
