Kolega Visage je dao dobar prijedlog, po primjerima poviše ja bih rekao da je printer sada u nekom drugom modu rada (prikazuje neke količine umjesto da printa).
Koliko se sjećam ta serija printera je imala svoj Setup / Konfig program kojim se namješatalo default postavke (PCL emulacija, veličina papira i ostalo). Probaj to naći i pokrenit na XP - u ili čak DOS - u, paoanta je da os ne ograničava direktnu komunikaciju programa sa printerom preko LPT - a.

Kad provjeriš default postavke sa DOS util - om, mora ti uredno štampat Self Test Page pokrenut na samom printeru. Vezano za poznate greške evo C/P sa wikipedie:
5L Printing Issues
* The 5L model sometimes doesn't print portions of the page or prints blurred letters. This is because the page being printed is taking up more memory than the printer has available. The solution is to either lower the resolution from 600X600 dpi to 300X300 dpi, install and use the 4L driver to print to the 5L printer, or install more memory using the expansion slot.
* If part of a page is replaced by lines (or, sometimes, a blank space like above), and then printed on another page, this is because of low memory. Typically, the 5L will give an error before this occurs (i.e. it will stop printing and turn on only the amber error light, but will continue if you hit the button). There are memory cards you can buy and install into the printer to solve this problem.
Dakle stavi drajver od 4L od HP - a (ne od winsa), postavi rezoluciju 300x300 (skoro nećeš ni primjetit razliku).
