It is difficult for me to say with certainty without seeing an example of the prints, but it sounds as if the black toner powder is not being printed. I say this as your printer should not be able to differentiate between text and graphics.
It is hard to say whether the toner cartridge or drum unit is the likely culprit, but you can probably get a good idea based upon what consumables have been changed recently.
The only other potential cause that springs to mind is that something in the configuration of whatever software you are printing from is set to only print images.

the body of text of the test page is black ink. From what you describe, the print heads are clogged. Most HPs use cartridges that have the head built in, but if not used for an externded period they can dry up and clog.
Try repeated head cleanings (10 or more) see if any change. If none, try new HP ink cartridges
If you have random blotches on both sides of the sheet, your printer probably needs cleaning, especially in the fuser section. If the fuser is difficult to get at, here's a good cheat developed for HP LaserJet 6 printers: Use a basic graphics program such as Microsoft Paint to draw three solid black rectangles about 2.5" top to bottom, going all the way across the paper (the space in between is not critical - the key is that you go as close to edge-to-edge as you can get). Print out this sheet.
Put the sheet back in the paper tray so it will print on the blank side (usually printed side up). Open up a quick text processor (Notepad in Windows). Type a single space, then print (some text editors won't print a document with no data in it). Dirt in the fuser will get stuck to the black areas on your cleaning sheet. Test your work by printing another copy of " ". Repeat with a new cleaning sheet if necessary.
Have you tried printing text in different colour if that works the black jets are blocked- try running the cleaning cycle to clear (it may not use black ink in graphics)
Trouble with the HP Laserjet printed output may be solved by using the following settings (or similarly named ones):
"Use raster Graphics" (instead of "Use vector graphics"). This may fix the problem of "reversed" text (white on black background) not printing, as well as other problems.
"Download TrueType Fonts as bitmap soft fonts" (select "bitmap" instead of "outline" or "graphics"). This may remove the overlapping of text on the printed document.
"Graphics dithering" select "coarse" or "fine" (instead of "none"). This selection may improve the quality of images contained in the document. You can find all these settings in your printer properties. Go to File, Print, click Preferences, in Printing Preferences, click one by one all the top options, and change one of the top solutions, one at the time, checking your printing output.
Always check if you have the latest version of Adobe Reader Program. If not download the latest version from Adobe, it's free.
Is this the first time that you have the problem? or with the same printer (HP 4si), did you were able to print PDF files in the past?
