Q106471

-

The information in this article applies to:

 * Microsoft Windows 3.1

SYMPTOMS
When printing an envelope from Word 2.x or 6.0 for Windows under Windows NT to a Hewlett-Packard (HP) LaserJet IIP or LaserJet IIIP, the printer will display the following message:

"MP LOAD COM10" Even when you have an envelope loaded into the MP (manual feed) tray, pressing the Online button will not resume printing. You must press and hold down the ALT key while pressing the Form Feed/Continue key.

CAUSE
By default, Windows NT will not select the manual feed tray for envelopes when printing on envelope size paper from any Windows application.

RESOLUTION
Use the following steps to associate envelope size paper with the manual feed tray so that Windows NT will know to select the manual feed tray when envelopes are printed:


 * 1) Start Windows NT Print Manager.
 * 2) Bring the desired printer window to the front.
 * 3) From the Printer menu, choose Properties.
 * 4) Choose the Setup button.
 * 5) Under the Source option, choose Manual Paper Feed.
 * 6) Under the Name option, choose Envelope #10.
 * 7) Choose OK.
 * 8) Choose the OK button in the Properties window.

MORE INFORMATION
Through Windows NT Print Manager, an administrator can assign particular paper sizes to particular paper bins on the printer. For instance, the administrator can specify that all letter-size pages printed from an application come from the upper tray, no matter which tray the document is formatted for.

More information on forms and how to set them is available in the "Microsoft Windows NT System Guide," pages 201 through 202.
