Tray 1 by default is set to any size, any type, which means that no matter what you print, it will pull from tray 1. You can change that by setting tray 1 for a specific size and type, such as 8.5" x 11"(Letter) and Plain paper, and then going into the print driver options (Control Panel, Printers & Faxes, right click on the HP 3550 and select Properties) and under the paper input tray, change it to either tray 2 or 3.

Ok remove tray 2, and in back its got a little clicking adjustable lever that you need to move so it lines up with letter 8.5 x 11...this worked for me

Step 1 : Change the print settings
The print settings of the HP All-in-One can be customized to handle nearly any print task.
Before changing the print settings, decide whether to change the settings for the current print job only, or to make the settings the default for all future print jobs. How print settings are displayed depends on whether to apply the change to all future print jobs or just to the current print job
Change the print settings for all future jobs:
In the HP Solution Center, click Settings , point to Print Settings , and then click Printer Settings .
Make changes to the print settings and click OK . Change the print settings for the current job:
On the File menu in the software program, click Print . Make sure that the HP All-in-One is the selected printer.
Click the button that opens the Properties dialog box. Depending on the software program, this button might be called Properties , Options , PrinterSetup , or Printer .
Select the appropriate options for the print job by using the features available on the Paper/Quality , Finishing , Effects , Basics , and Color tabs.
Click OK to close the Properties dialog box. Click Print or OK to begin printing.
Step 2 : Print with 210 x 297 mm (8.5 x 11 inch) labels
The HP All-in-One can be used with any software program designed for printing.
This document contains basic information about using the HP All-in-One to print on labels using a software program. For additional information, such as printing a poster, printing multiple pages on a single sheet, and more, see the onscreen Help that came with the HP software.
Follow these steps to print on labels:
· Make sure to load labels in the input tray. Always use letter or A4 label sheets designed for use with HP inkjet devices (such as HP inkjet labels).
· Make sure the labels are no more than two years old. Labels on older sheets might peel off when the paper is pulled through the HP All-in-One, causing paper jams.

• Fan the stack of labels to make sure no pages are sticking together. Place a stack of label sheets on top of full-size sheet of plain paper in the paper tray, label side down. Do not insert labels one sheet at a time.
1. On the File menu in the software program, click Print . Select the HP All-in-One as the printer. To change settings, click the button that opens the Properties dialog box.
2. Select the appropriate options for the print job by using the features available on the Paper/Quality , Finishing , Effects , Basics , and Color tabs.
3. Click OK to close the Properties dialog box. Click Print or OK to begin printing.

Open a document. Select File>Page Setup and change the Source to Tray 4.

Or...

Try to print something. When the Print window comes up, select Preferences. On the Print/Quality tab look for the drop down menu labeled "Source is:" and change it to the tray you want. Click on the Save button.
