product used in an hp laserjet 200 all in one printer. the bulk of the printing is generated by my 1st grade school teacher wife who is constantly required to use our own resources because of budget cutbacks, or reallocated school board authorized funds. it's a tough deal when at the beginning of the school year each teacher is given a (1) ream of paper for the school year for their copies and then they have to either wait in line for the copier or it is down because they can't get funds to replace the toner cartridge in a timely manner. super media has been a tremendous source of economical printer supplies that helps take the bite out of funding the necessary school projects in addition to our own home use printing requirements. glad i found this place and their great and reliable products.
