Question about HP LaserJet 4L Printer
My 4l has worked fine for many years. But I recently encountered this problem: I try to print a page and it gets to the print queue, but won't print. I've tried the troubleshooter but it didn't help. I can force a printed page by hitting the button on the left hand side. The problem seems to be between the computer and the printer.
Try borrowing another suitable printer lead and test with that. If the printer can do a self test, it is likely the printer is not the problem. If that does not work, if you can, use another printer with your computer - but set it up first. Failing that come back for more help

Check your Toner Carts.
Is the line a certain color?
Lift the door of the toner cart.
If you see a streak on your toner drum, you will see a streak on your paperwork.
Look at your fuser as well.
Is there a problem with the big orange roller?
BEWARE! Don't touch the fuser roller its EXTREMELY HOT!
Let the printer cool down before inspecting.

Well lets start with DISREGARD ALL THE ABOVE BULL in the above brainless clarification request first noted. Here's a little good advice for you from a 14 year veteran printer tech.
Lets start with the cheapest and easiest moving to the more difficult or more expensive. Your problem can be caused by a few differnt things.
Print a configuration page (on the printer menu press check button, scroll to info menu, press check, scroll to print configuration, press check. Once you have the look for the page count on the page.
Try fresh good paper from a sealed ****. If your paper has picked up moisture this will show up as light or uneven print.
Next if the printer is over 100K page count, replace the transfer roller (foam roller inside printer under the toner cartridge). Lets try cleaning it first if your under 100K or to see if it improves at all. Any improvement will verify the transfer roller as bad. Review the photo below as it shows the transfer roller end inside the printer. The screwdriver is showing where the release white clips are (two). Press the tabs and lift the left side. The right will come out of the hole socket on its own but note where the hole on the right is for replacement. Try not handling the roller with your bare hands any more than you must as oil from your hands can cause slight imaging defects if your hands are sweaty or damp.
Using a clean rag (like t-shirt material) dampened (not soaking) with 99% alcohol (not 70%) lets clean the roller. Gently but firmly scrub the talc and paper dust buil-up from the roller. Once you've removed the build up it should return to a dark grey color. Let the 99% alcohol dry (5 minutes or so)and reinstall.
Try printing again. If the problem is solved your done. If not and it has improved, you will need a new transfer roller. They are available on Ebay much cheaper than from a dealer. The part number to search for is RM1-0343. Here's a link to ebay for one at around $20.00 landed.
If the problem is the same, your problem is more than likely a dirty laser scanner lense. You'll need to remove the covers from the printer to accomplish this. The laser scanner can be located under the top cover. It's the larger black box on the top side of the printer. Once the scanner has been located, remove the top cover. DO NOT TOUCH THE MULTI SIDED SPINNING MIRROR TO THE REAR OF THE SCANNER. You will be cleaning the clear lenses and mirror towards the front. You clean this gently with a CLEAN and DRY Q-tip. Use a few Q-tips rather than re-applying a dirty one. Heck they are cheap!
Re-assemble the printer and try printing again. One of the steps above should resolve your issue. I am enclosing a link to a free service manual for your printer to help you through the disassembly and in the rare case that your issue remains.
Hope this helps you a lot more than the first response you receved. If so rate me with a FIXYA!

SOURCE: printer queue is full
This problem seems to be related to USB printers and print queue issues are very common in Mac OS computers and Windows 2000 PCs.
You don't say if you are using a USB connector, but they're pretty common these days. You also don't say if you're using a Mac or PC, but most people use PCs. I did find a solution for this issue that says it's related to Windows 2000 and a USB printer, but may apply to other operating system platforms:
Print Jobs are Stuck in the Print Queue
The first step to this solution is to download and install an HP diagnostic software utility. There's a separate page at HP that describes the utility and lets you download it:
HP Printing and Diagnostic Utility
I didn't find any information that specifically said that you "can" print a test page but "can't" print a document.
Another reason why you might be able to print a test page but not a document isn't related to the printer but the application that created the document. If you are having trouble with Word or Excel or whatever office application you used to create the doc, it might not print. That's why it is helpful to try to print a variety of different docs, created with different apps.
It could also be the individual document. Occasionally, a document becomes corrupted and while you may be able to open it (and sometimes you can't do even that), it doesn't print. If you haven't tried printing more than one document, you can test this by creating another doc in the same app and seeing if it'll print.
Try doing test prints with different docs and then with docs created in different apps. If those work, it's doc/app related. If they don't, try the links I suggested above.
