Abstract
The printer is provided for alternative use with long webs or individual, precut forms; it includes two friction roll drives adjacent to the print head and platen, and a sprocket drive upstream, being permanently engaged with a perforated web. The drives operate in synchronism but do not participate in all operations. Printing on the web is carried out after advancing the web by one form length and retracting it during stop and go printing. Switches control access to a bypass, the insert for a single form, and a receiver tray, into which any printed form drops.
