How to print a custom size paper on HP Laserjet 2550 I used to be able to print pretty much any size of the paper with this printer, but now, I can not even find the ''Custom'' for the paper size in the printer control panel. Please advice!!

Please check your paper tray adjustments and verify that the paper type for the tray is set to any type or plain (assuming you are printing on plain paper). In general, if the machine has reason to believe that there is a custom size or special type of media, it prints at half speed.

The minimum size paper or envelope for tray 1 is 76 x 127mm (3 x 5).
The weight should be between 75 to 105 g/m2 (20 to 28 lb)

Do NOT use customized paper. Set your paper tray to LEGAL paper. Set the tray as LEGAL in the printers setup-menu. Make sure you choose LEGAL in the printout-dialog-properties. Then it should work. Good Luck.

check to see if there is a custom size option on the page setup on the print job. that might work.

When installing new cartridges, it's always a great idea to perform a cleaning and recalibration of the machine. Below are the steps needed to do just such a task. You may want to print these out or save them somewhere for future reference as well. They are directly from the HP website.

Look on the left side of the tray. There should be 3 white fingers that stick out. Make sure they aren't broken or out of place. Also slide the paper size lever and make sure they work properly. There is also a custom and standard switch. Try to print out of the MP tray(fold down tray). If it prints normal speed, you probably have a problem with the tray.
