Very economical printer

I have been using one of these printers for the past year and have found it very economical in delivering crisp, black only pages. On average I print about 40 pages per day and a re-manufactured cartridge lasts as long as 6 months before replacement is required.
This printer has a host of features including a separate loading bay for envelopes and a generous one for plain paper. While it does have a reasonable footprint, the printer is also more versatile as the pages can be collected from either the top in the order it was to be printed or directly onto the desk surface.
Of note, the printer driver can cause pages printed from Internet Explorer to return a blank sheet after the intended page is printed. On-line help suggests re-installing the driver, which does not always work.
