Well, I don't have better guesses at the moment besides faulty usb hardware on the side of the router. Sorry.
I have tested the router with an HP Laserjet 1010. I have connected de HP 1010 with an USB cable to the router. De router recognized the HP laserjet 1010 immediately without any commands with Telnet! Then I have maked an new networkprinter under Windows XP and Ubuntu 9.10. There where on both operation systems no errors. Printing was no problem!

Code:
Nov 28 16:45:30 kernel: hub.c: new USB device 01:03.0-1, assigned address 2
Nov 28 16:45:30 kernel: printer.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 1 proto 2 vid 0x03F0 pid 0x0C17
Nov 28 16:45:30 kernel: printer.c: usblp0 Device ID string [143]='MFG:Hewlett-Packard;CMD:PJL,MLC,BIDI-ECP,DW-PCL;MDL:hp LaserJet 1010;CLS:PRINTER;DES:Hewlett-Packard LaserJet 1010;MEM:5MB;COMMENT:RES=600x1;'
I have tested the internal chip from the 1010 in de 1020. The printer didn't work. Also tested the internal chip from the 1020 in the 1010 but then I get also problem's (printers doesn't work at al)

So the only solution was to exchange the printers to "solve" this problem.
Now I have exchanged the HP Laserjet 1020 with a HP Laserjet 1010. The 1020 and 1010 are using the same toner so that maked it easy.
