Commenting on some very healthy first quarter figures Lexmark International Inc warns that year-to-year comparisons for the rest of the year could be made more difficult by several factors, including lower gross profit margins in other office imaging products as a result of new contractual arrangements with IBM Corp, and elimination of revenues following the company’s exit from the keyboards business, which occurred as planned at the end of last month; downward pressures on both laser and inkjet printer prices are expected, and the inkjet market has recently experienced significant printer price pressure from major competitors, while new competitive laser printer announcements are expected in the very near future.
